Cooper Avenue, East Cooper Court Unit A- Minor Development, Public Hearing DATE: June 23, 2004 SUMMARY: The subject property is a 10,500 square foot lot that is listed on the Aspen Inventory of Historic Landmark Sites and Structures. In 1995, HPC approved a project that involved the on-site relocation and rehabilitation of the Victorian era home which sits on this site, along with a contributing barn. Three additional homes were approved for construction, the last of which was recently reviewed. The board is asked to grant Minor Development approval for a deck extension on the non-historic addition to the Victorian. The applicant has been before the board for a worksession to discuss this plan. Staff finds that the project complies with the applicable review standards and recommends approval. APPLICANT: Maurice Herman, owner, represented by Gilbert Sanchez, architect. PARCEL ID: 2737-182-52-001. ADDRESS: 949 E. Cooper Avenue, East Cooper Court Unit A, Block 37, City and Townsite of Aspen. ZONING: RMF (Residential Multi Family). MINOR DEVELOPMENT The procedure for a Minor Development Review is as follows. Staff reviews the submittal materials and prepares 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 I _ ,,__,"__'~'m~""_'_'___":' __.~.__~____",., N'_.~__' ....~...."_"....".__...M_.'....~.__..... "...~._"~~_.".'" analysis report and the 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. If the application is approved, the HPC shall issue a Certificate of Appropriateness and the Community Development Director shall issue a Development Order. The HPC decision shall be final unless appealed by the applicant or a landowner within three hundred (300) feet of the subject property in accordance with the procedures set forth in Chapter 26.316. Staff Response: The request is that HPC approve an extension of the deck that is on the west side of the non-historic addition to this house. A list of the design guidelines relevant to this Minor Review is attached as "Exhibit B." During a worksession, the board expressed concerns with the proximity of the deck to the historic side porch. Because the addition to this house was designed before the adoption of the current design guidelines, there is not as much separation between the historic resource and addition as would generally be preferred. Arguably, the existing deck in its current configuration is somewhat competitive with the front porch as viewed from the west elevation although it's small size and cantilevered design are mitigating factors. It appears that the deck is far enough back from the street that the expansion will have minimal impact from the front elevation. There is some visibility of the west elevation because the house sits on a courtyard. One guideline that may deserve some consideration is: 10.3 Design a new addition such that one's ability to interpret the historic character of the primary building is maintained. Cl A new addition that creates an appearance inconsistent with the historic character of the primary building is inappropriate. Cl An addition that seeks to imply an earlier period than that of the primary building also is inappropriate. Cl An addition that seeks to imply an inaccurate variation of the primary building's historic style should be avoided. Cl An addition that covers historically significant features is inappropriate. In truth, the integrity of the Victorian home that is affected by this project is solely its overall shape, which is historically accurate. Perhaps particularly because of this circumstance, Staff does share HPC's concern with allowing new construction to start to visually encroach on the house, which it appears this deck does, at least from some perspectives. Staff recommends the project be continued with the direction that the deck may be expanded towards the south, but any increase towards the west must be restudied to create some separation from the historic porch. 2 .."__._.~_._., ,~'"'''_''' _____.._,..._,___,~ ,...................'~___w.

Cl A new addition that creates an appearance inconsistent with the historic character of the primary building is inappropriate. Cl An addition that seeks to imply an earlier period than that of the primary building also is inappropriate. Cl An addition that seeks to imply an inaccurate variation of the primary building's historic style should be avoided. Cl An addition that covers historically significant features is inappropriate. 10.4 Design a new addition to be recognized as a product of its own time. Cl An addition should be made distinguishable from the historic building, while also remaining visually compatible with these earlier features. Cl A change in setbacks of the addition from the historic building, a subtle change in material or a differentiation between historic, and more current styles are all techniques that may be considered to help define a change from old to new construction. 10.8 Place an addition at the rear of a building or set it back from the front to minimize the visual impact on the historic structure and to allow the original proportions and character to remain prominent. Cl Locating an addition at the front of a structure is inappropriate. Cl Additional floor area may also be located under the building in a basement which will not alter the exterior mass of a building. Cl Set back an addition from primary facades in order to allow the original proportions and character to remain prominent. A minimum setback of 10 feet on primary structures is recommended. 10.10 Design an addition to a historic structure such that it will not destroy or obscure historically important architectural features. Cl For example, loss or alteration of architectural details, cornices and eave1ines should be avoided. 10.11 On a new addition, use exterior materials that are compatible with the historic materials of the primary building. Cl The new materials should be either similar or subordinate to the original materials. 4 -rx /I , MEMORANDUM TO: Aspen Historic Preservation Commission FROM: Amy Guthrie, Historic Preservation Officer RE: 403 W. Hallam Street- Major Development Review (Conceptual) and Variances- Public Hearing DATE: June 23, 2004 SUMMARY: The subject house was constructed before 1893 and is listed on the Aspen Inventory of Historic Landmark Sites and Structures. The owner requests approval to demolish a non-historic garage, to construct an addition to the existing residence, and to make minor modifications to the historic residence. Setback variances and a Residential Design Standard variance are needed. HPC held a worksession regarding this project on May 26th, at which time the applicant requested feedback on whether an FAR bonus would be appropriate as part of their plan to create TOR's from the remaining development potential on the site. The board was supportive of the idea and the application in general. Staff finds that some modifications to the project are necessary, hut these can be handled as conditions of Conceptual approval, which is recommended to he granted. APPLICANT: Mary Janss and Stan Gibbs, represented by Joede SchoeberIein of Civic Forum. PARCEL In: 2735-124-33-005. ADDRESS: 403 W. Hallam Street, Lot I and the east half of Lot H, Block 36, City and Townsite of Aspen, Colorado. ZONING: R-6. MAJOR DEVELOPMENT (CONCEPTUAL) The procedure for a Major Development Review, at the Conceptual level, is as follows. Staff reviews the submittal materials and prepares 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 the 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. 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. Staff Response: Recently, the HPC has been contemplating new tools to analyze the appropriateness of proposals to alter historic structures. The following questions are likely to be the center of future discussions, and may be helpful for HPC to at least reference for this project (note that the questions do not serve as formal decision making criteria at this time): 1. Why is the property significant? 2. What are the key features of the property? 3. What is the character of the context? How sensitive is the context to changes? 4. How would the proposed work affect the property's integrity assessment score? 5. What is the potential for cumulative alterations that may affect the integrity of the property? The miner's cottage on this property is significant as an example of typical modest housing built in the Victorian period. The key feature of the property is that the cottage is intact in terms of its original form and scale, something of a rarity here. Alterations have been made to some window openings and features, but overall, this is a good example from the period. There are a number of other Victorian era homes that remain in the immediate area. The property's integrity score should be improved by this project given the fact that some restoration work will take place on the front porch and exterior materials. The house will not be subject to any significant additions in the future because only a very modest amount of square footage will remain after this project is built. Desi2n Guideline review Conceptual review focuses on the height, scale, massing and proportions of a proposal. A list of the design guidelines relevant to Conceptual Review is attached as "Exhibit B." Only those guidelines which staff finds warrant discussion are included in the memo. The proposal is to demolish a non historic garage, construct a new addition, and make some alterations to the miner's cottage. 2 Overall, staff finds that the project is compliant with the design guidelines. The footprint, height, and roof forms of the addition are sympathetic to the historic house. The addition is one story in height for some distance behind the cottage, which provides a very successful transition to the taller area along the alley. There are two aspects of the proposed alterations to the miner's cottage which are topics for Conceptual review. The first is the re-opening of the original porch. This is a very positive change to the condition of the house and is supported by the guidelines. Staffs only concern is that the rebuilt porch be based on factual evidence about its design to the greatest extent possible. The owners have been informed by an earlier resident that the porch, as he remembers it from several decades ago, was as they show in their plans. However, the Sanborne maps, and a photograph of the house immediately to the west before it underwent a very destructive renovation, indicate that the porch originally had a different layout. It is clear in looking at the subject house that its foundation does not match the rest of the building, supporting the idea that the shape that it has today is not original. Staff recommends the plans be amended to rebuild the porch in the following manner: ',' "D j '" frT"] ! :1 , ~" :z r ;/L;';...LI r i, .. [7 1904 Sanborne Map showing identical homes and porches at 403 & 407 W. Hallam Front porch at 407 W. Hallam pre- renovation. Based on comments made at the worksession, the architect plans to continue to study restoration of the front porch and will provide new drawings for HPC to discuss. The second part of the proposed work on the miner's cottage at 403 W. Hallam Street that was debated at the worksession was the addition of new dormers. Two are proposed; one on the east elevation, on the non-historic part of the house, and one on the west elevation, on the historic front gable end. The house currently has attic living space and the owner wishes to improve the livability of this area. The guidelines related to dormers are: 3 "-~'""---"-_..----. ......., "-'._"~-~---._----" 7.7 A new dormer should remain subordinate to the historic roof in scale and character. D A new dormer should fit within the existing wall plane. It should be lower than the ridgeline and set in from the eave. It should also be in proportion with the building. D The mass and scale of a dormer addition must be subordinate to the scale of the historic building. 10.12 When constructing a rooftop addition, keep the mass and scale subordinate to that of a historic building. D An addition should not overhang the lower floors of a historic building in the front or on the side. D Dormers should be subordinate to the overall roof mass and should be in scale with historic ones on similar historic structures. D Dormers should be located below the primary structure's ridgeline, usually by at least one foot Staff is not concerned with the dormer on the east because it is not affecting the historic part of the building. The dormer that will become a part of the front fayade of the building is more of an issue because it impacts one's perception of the simplicity of the design of the house. Dormers were not used on Aspen's miners cottages originally. Some higher style buildings have them, however it appears that they were always paired, not used as a single element as is proposed in this project. HPC appeared to have a similar concern at the worksession. As stated, the attic has been in use for some time. The owner is not proposing to build a basement under the miner's cottage, so space is at a premium. After discussing the project with the Chief Building Official, it appears though that in terms ofIRC compliance, it is not necessary to add more natural light to these rooms. Egress is needed from the area where a bedroom is indicated, and the CBO has confirmed that the "new larger window" indicated in the historic west facing gable end of the house will be adequate. The west dormer will not be required so Staff has recommended its elimination. The owner has a significant concern with fire safety and an HPC member suggested the possibility of installing sprinklers in the building as an extra security measure. This is being pursued and the architect has informed staff during the preparation of the memo that the west dormer is being removed from the project. Skylights are also proposed to be located on the historic roof and will be discussed at Final review. Typically they have not been permitted on historic buildings, or at least only are allowed in very obscure locations. DEMOLITION OF THE GARAGE The plan includes a proposal to demolish the single car garage that faces Third Street. Building Department records show that this structure was built in 1956. Demolition shall be approved if it is demonstrated that the application meets anyone ofthe following criteria: 4 a. The property has been determined by the city to be an imminent hazard to public safety and the owner/applicant is unable to make the needed repairs in a timely manner, b. The structure is not structurally sound despite evidence of the owner's efforts to properly maintain the structure, c. Aspen, or The structure cannot practically be moved to another appropriate location III d. No documentation exists to support or demonstrate that the property has historic, architectural, archaeological, engineering or cultural significance. Additionally, for approval to demolish, all of the following criteria must be met: a. The structure does not contribute to the significance of the parcel or historic district in which it is located, and b. The loss of the building, structure or object would not adversely affect the integrity of the historic district or its historic, architectural or aesthetic relationship to adjacent designated properties and c. Demolition of the structure will be inconsequential to the historic preservation needs of the area. Staff Response: The garage is not related to the period of significance for the Victorian, and has no special architectural merit, so staff finds that the above criteria are met and supports removal of the building in favor of allowing for a well designed addition. FAR BONUS The applicant is requesting a floor area bonus that will be applied to the square footage that is built on the site and will result in a balance that can be sold in the form of two 250 square foot TOR's. Based on the information contained in the application, the bonus needed to accomplish this is 376 square feet. The following standards apply to an FAR bonus, per Section 26.415.IIO.E: 1. In selected circumstances the HPC may grant up to five hundred (500) additional square feet of allowable floor area for projects involving designated historic properties. To be considered for the bonus, it must be demonstrated that: a. The design of the project meets all applicable design guidelines; and b. The historic building is the key element of the property and the addition is incorporated in a manner that maintains the visual integrity of the historic building and/or c. The work restores the existing portion of the building to its historic appearance; and/or d. The new construction is reflective of the proportional patterns found in the historic building's form, materials or openings; and/or e. The construction materials are of the highest quality; and/or 5 f. An appropriate transition defines the old and new portions of the building; and/or g. The project retains a historic outbuilding; and/or h. Notable historic site and landscape features are retained. 2. Granting of additional allowable floor area is not a matter of right but is contingent upon the sole discretion of the HPC and the Commission's assessments of the merits of the proposed project and its ability to demonstrate exemplary historic preservation practices. Projects that demonstrate multiple elements described above will have a greater likelihood of being awarded additional floor area. 3. The decision to grant a Floor Area Bonus for Major Development projects will occur as part of the approval of a Conceptual Development Plan, pursuant to Section 26.415.070(D). No development application that includes a request for a Floor Area Bonus may be submitted until after the applicant has met with the HPC in a work session to discuss how the proposal might meet the bonus considerations. Staff Response: Staff finds that all of the criteria except "g" are being met. The scale and siting of the addition are excellent, and the addition in no way "hovers" over the historic house as has unfortunately been the case in some past projects. The miner's cottage is being restored and street facing open space is left around the building much as it exists today. A bonus in the amount needed to allow the property to benefit from the sale of two TOR's, which may help to fund some of the restoration work, is appropriate. SETBACK VARIANCES The project includes requests for the following setback variances: a 2 foot west sideyard setback reduction for the new addition, a 5 foot east sideyard setback reduction only to allow for a lightwell, a 7 foot combined sideyard setback reduction due the proposed lightwell, and a 5 foot rear yard setback reduction for the new addition. The criteria, 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; and/or 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 Response: The setback variances, particularly the west and rear yard variances, are important in that they allow the addition to be set back as far as possible on the lot, creating a cushion of space around the historic house. The east sideyard setback variance and combined sideyard variance are necessary because of a lightwell. Staff does have some concerns with the size and location of the east lightwell, in part because it does not comply with a Residential Design Standard. The Residential Design 6 Standards state that "All areaways, lightwells and/or stairwells on the street facing fayade(s) of a building shall be entirely recessed behind the frontmost wall of the building." In this case, the lightwell projects closer to Third Street than the addition does. In order to receive a variance from the standard, which applies to all residential development, it must be found that the variance, if granted 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 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. In order to better comply with both the setback requirements and the Residential Design Standards, Staff recommends that there be discussion of the opportunity to either reduce the size of this lightwell or move it to the north or south side of the building per the following HPC guideline. 9.7 A Iightwell may be used to permit light into below-grade living space. D In general, a lightwell is prohibited on a wall that faces a street (per the Residential Design Standards). D The size of a lightwell should be minimized. D A lightwell that is used as a walkout space may be used only in limited situations and will be considered on a case-by-case basis. If a walkout space is feasible, it should be surrounded by a simple fence or rail. 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 grant Major Development (Conceptual) and Variances for 403 W. Hallam Street, Lot I and the east half of Lot H, Block 36, City and Townsite of Aspen, Colorado with the following conditions: 7 I. The front porch is to be constructed in the most historically accurate configuration. 2. The proposed dormer is to be eliminated from the west side of the historic house. (This has apparently been agreed to.) 3. HPC hereby grants the following variances: a 2 foot west sideyard setback reduction for the new addition and a 5 foot rear yard setback reduction for the new addition. Subject to discussion at the meeting of other reasonable options related to the east lightwell, the HPC may also grant a 5 foot east sideyard setback reduction, a 7 foot combined sideyard setback reduction and a variance from the Residential Design Standards related to lightwells. 4. HPC hereby grants an FAR bonus of 376 square feet in order to ultimately allow for the creation of two TOR's from this property. The bonus is not approved for additional construction beyond what is represented in the plans currently under review. 5. A development application for a Final Development Plan shall be submitted within one (I) year of the date of approval of a Conceptual Development Plan. Failure to file such an application within this time period shall render null and void the approval of the Conceptual Development Plan. The Historic Preservation Commission may, at its sole discretion and for good cause shown, grant a one-time extension of the expiration date for a Conceptual Development Plan approval for up to six (6) months provided a written request for extension is received no less than thirty (30) days prior to the expiration date. 6. A landscape plan, lighting, fenestration and detailing, selection of new materials, and technical issues surrounding the preservation of existing materials will all be addressed at Final Review.

Hallam Street, Conceptual Review" 5.3 Avoid enclosing a historic front porch. D Keeping an open porch is preferred. D Enclosing a porch with opaque materials that destroy the openness and transparency of the porch is not acceptable. D Enclosing porches with large areas of glass, thereby preserving the openness of the porch, may be considered in special circumstances. When this is done, the glass should be placed behind posts, balusters, and balustrade, so the original character of the porch may still be interpreted. D The use of plastic curtains as air-locks on porches is discouraged. D Reopening an enclosed porch is appropriate. 7.7 A new dormer should remain subordinate to the historic roof in scale and character. D A new dormer should fit within the existing wall plane. It should be lower than the ridgeline and set in from the eave. It should also be in proportion with the building. D The mass and scale of a dormer addition must be subordinate to the scale of the historic building. 8.1 If an existing secondary structure is historically significant, then it must be preserved. D When treating a historic secondary building, respect its character-defining features. These include its primary and roof materials, roof form, windows, doors and architectural details. D If a secondary structure is not historically significant, then its preservation is optional. 9.7 A Iightwell may be used to permit light into below-grade living space. D In general, a lightwell is prohibited on a wall that faces a street (per the Residential Design Standards). D The size of a lightwell should be minimized. D A lightwell that is used as a walkout space may be used only in limited situations and will be considered on a case-by-case basis. If a walkout space is feasible, it should be surrounded by a simple fence or rail. 10.3 Design a new addition such that one's ability to interpret the historic character of the primary building is maintained. D A new addition that creates an appearance inconsistent with the historic character of the primary building is inappropriate. D An addition that seeks to imply an earlier period than that of the primary building also is inappropriate. D An addition that seeks to imply an inaccurate variation of the primary building's historic style should be avoided. D An addition that covers historically significant features is inappropriate. 10.4 Design a new addition to be recognized as a product of its own time.

D An addition that is lower than or similar to the height of the primary building is preferred. 10.7 If it is necessary to design an addition that is taller than a historic building, set it back substantially from significant facades and use a "connector" to link it to the historic building. D A I-story connector is preferred. D The connector should be a minimum of 10 feet long between the addition and the primary building. D The connector also should be proportional to the primary building. 10.8 Place an addition at the rear of a building or set it back from the front to minimize the visual impact on the historic structure and to allow the original proportions and character to remain prominent. D Locating an addition at the front of a structure is inappropriate. D Additional floor area may also be located under the building in a basement which will not alter the exterior mass of a building. D Set back an addition from primary facades in order to allow the original proportions and character to remain prominent. A minimum setback of 10 feet on primary structures is recommended. 10.9 Roofforms should be similar to those of the historic building. D Typically, gable, hip and shed roofs are appropriate. D Flat roofs are generally inappropriate for additions on residential structures with sloped roofs. 10.10 Design an addition to a historic structure such that it will not destroy or obscure historically important architectural features. D For example, loss or alteration of architectural details, cornices and eavelines should be avoided. 10.12 When constructing a rooftop addition, keep the mass and scale subordinate to that of a historic building. D An addition should not overhang the lower floors of a historic building in the front or on the side. D Dormers should be subordinate to the overall roof mass and should be in scale with historic ones on similar historic structures. D Dormers should be located below the primary structure's ridgeline, usually by at least one foot. 10 14.17 Design a new driveway in a manner that minimizes its visual impact. D Plan parking areas and driveways in a manner that utilizes existing curb cuts. New curb cuts are not permitted. D If an alley exists, a new driveway must be located off of it. 14.18 Garages should not dominate the street scene. 14.20 Off-street driveways should be removed, iffeasible. D Non-historic parking areas accessed from the street should be removed if parking can be placed on the alley. 14.22 Driveways leading to parking areas should be located to the side or rear of a primary structure. D Locating drives away from the primary facade will maintain the visual importance the structure has along a block.

Box 550, Aspen, CO 81612 e-mail cvcforum@sopris.net , G) @ Aspen Historic Preservation Design Guidelines - Compliance memo 403 West Hallam 403 West Hallam is included on the Aspen Inventory of Historic Landmark Sites and Structures. The applicant proposes to rehabilitate the existing listed structure in order to restore an appearance closer the original, to make repairs that will protect the asset and to add a major new addition to the rear of the existing house. Proposed work: Existing structure: The work will involve removal of a non-original enclosed front porch and its replacement with an open porch similar to what appears to have been the original configuration. The current aluminum siding will be removed and replaced with new wood lap siding and square trim as appears to be the original finish of the house. Existing trim and cut shingle siding (high in gable ends) will be rehabilitated and repaired or replaced where no longer existing. Other non-original additions will receive finishes that are different, but compatible with those on the original house in order to distinguish these additions from the original structure. The applicant also proposes to reconfigure some of the upper floor to increase the utility of this space. As part of this work we are proposing adding dormers and skylights to bring appropriate light, ventilation and safe egress to these spaces. New Addition: This project includes constructing a substantial addition on the rear portion of the site to accommodate a new garage and a master suite. The major portion of this addition has been pulled to the rear of the site to maximize the separation form the original house. The addition is being designed in a different style and with different finish materials to distinguish its identity from the original house. Style and Design: This structure is a classic example ofa modest Vernacular Wood Frame "Miner's Cottage". It was most likely constructed in the 1880's and first appeared on the city surveys of 1891. The original structure had a slightly asymmetrical gabled cross plan. The existing original roofs were all 14/12 pitch. The house was originally one story with an unfinished attic space. The two gabled profiles facing the streets on this corner site, feature simple projecting rectangular bay windows. The rest of the original windows are tall slender double hung. The original siding is believed to have been lap wood clapboard, though none of this original material remains. The gables feature a trim bordered area of chamfer-ear cut shingles that appears to be original. The small roofs over the bay windows were also finished in this material. The roof is, and probably was originally, standard cut wood shingles, although none of the original roofing remains. The trim and ornamentation was fairly simple. What remains of the corner trim is square cut, there are built up milled profiles at the eaves and some fairly basic ornamented Page I of8 ~._.~-----,~" -,""., ~"-"-,- "'-'--"_,,,~ brackets under the bays. The original (no longer existent) porch was probably a filigree type structure that included lathed spindles and columns as is common throughout the town in this type of structure. The entire back portion of the house (the rear leg of the cross) was replaced in 1954 with a somewhat bulky addition of the full width of the plan with a lower asymmetrical roof pitch. The portion of this addition facing the side street has the appearance of an enclosed porch, however there is no evidence that it was ever open. This addition included a second floor. In 1961 the original front porch was removed and the area was enclosed as part of the front room. The aluminum siding was installed and some of the double hung windows were changed to casements and pictures. In 1966 the second floor was further extended into the original portion of the house by lowering the ceiling in one of the original rooms. A second floor window was added on the west wing of the original house at this time. At this time the upstairs and downstairs bathrooms were added. If there was any bathroom in the house prior to this, its location and configuration are not known. In 1969 the house was re-roofed and a ventilated roofwas added over the entire house including the original roof and that on the additions. The edges were finished with more built up trim in the character of the original profile. The roof still has very little insulation and there are considerable problems with ice dams, icicles (river sized), and leaking. The parcel also includes a shed style garage built in 1956. The garage is at the Southeast corner of the lot and is partially in the street R.OA and alley. Streetscape and Lot Features: The street-planting strip consists oflawn and street trees consistent with the traditional pattern. There is no sidewalk except for a small stretch from the rear gate to the garage entry. This section of sidewalk was installed in 1957. The rear portion of the yard is fenced with a looped woven wire and post fence. A portion of the street planting strip adjacent to the garage and back yard has been paved with asphalt. The yard is mostly lawn with some flowerbeds and trees and shrubs. The applicant is not proposing any changes to the street- scaping except to remove the paving and replace it with grass. The front and rear door walks will be replaced and extended to reach the street. All of the mature trees within the yard will be preserved. Some recently planted young aspen trees will be displaced by the addition and relocated on the property. The fence will be reconfigured slightly to accommodate the configuration of the addition. A small amount of solid fence is proposed on the alley side to protect the window well at that location. Page 2 of8 Historic Building Materials: '-,/ The bulk of the siding was removed and replaced, probably a couple of times. The current siding is broad aluminum clapboard. The original principal siding appears to have been wood clapboard, though none of this material remains. The upper portions of the exterior walls still include some trim and shingle siding that appears to be original. This project will include replacing the aluminum siding with wood clapboard to match what we believe to have been the original appearance consisting of square trim corners and a horizontal clapboard field. The portions of the trim and shingle siding that remain will be reconditioned and restored in place. Replacement will be limited to those pieces that are beyond repair and will be done with materials in kind. The foundation consists of mortared rubble stone, which appears to be in good condition. The foundation will be reconditioned and restored in place as required. Replacement will be limited to those pieces that are beyond repair and will be done with materials in kind. Windows: Many of the original windows remain and will be retained in the rehabilitation of the original structure. These windows will be reconditioned and restored in place. The 2nd floor of the rear addition currently includes a picture window with flanking casements. As part of the effort to restore an appearance and proportion closer to the original house, these non-characteristic windows will be replaced with a pair of new double hung windows. These new windows will match the original windows as close as is feasible with a new manufactured window. Another non-original double casement window on the ground floor of the old addition will be displaced with a french door. (This is near the rear side fence and is not visible from the street or alley. The small double hung on the 2nd floor west gable is a modem window and we plan to replace it with a larger window, more in line with the scale of the original windows. Doors: The house currently has two exterior doors. Neither is original, nor are they in original locations of exterior doors. The door on the old rear addition will remain as is. The front door that is located on the filled-in front porch is a contemporary panel door. Since the porch is being restored to an open configuration this door location is eliminated. The new front door will be in a new replacement wall located where the original wall was and a new door will be located where we believe the original was located. A new double arch top glass paneled door will be installed in this location. This new door will match the style of what we believe the original exterior doors to have been. A transom will be installed over this door as we believe to have been the original configuration. Porches: This house appears to have originally had an open covered front porch. This porch was eliminated in 1961 and replaced with an expansion of the existing front room. In this project we propose restoring the porch with a structure we believe to be consistent with the original configuration. Since there are no known photographs of the original porch we are basing the design and details of this replacement structure on other existing examples in the area and period photographs of other structures. The style of the Page 3 of8 replacement porch will be simple, but will include some basic ornamentation in the form - of turned spindles and corner post as we believe to have been included in the no longer existing original. There were likely two doors from this porch to the interior. This project will place a door approximately where one of them likely was located. Architectural details: All of the existing original materials and architectural details will be retained in place and restored and repaired where possible. Replacement of original materials will be limited to those beyond repair. We do not anticipate needing anything more than limited selective replacement as what original material and detail remains appears to be in generally good physical condition. The bulk of the siding and trim was removed many years ago. The non-original siding will be replaced with new material and detail matching what we believe to have been the original configuration. Roofs: The original roofs were steeply pitched and appear to have been finished in cedar shingles. The entire original roof was covered by adding furring and a new roof surface to create a vented roof. The current roof is finished in wood shingles though none it is the original material. The current roofing is in poor condition and it leaks. This project will include reproofing the entire existing house with new material so that the finish matches the presumed original appearance. Secondary Structures: At the present time there is a single car garage built in 1956 that is much younger than the original house. Interviews with the previous owner indicate that this structure was preceded by a couple of freestanding sheds at the edge of the alley. The garage was covered, until recently with asphalt shingle material that matched that on the house before the aluminum siding was added. This project will displace the garage structure although the principal volume of the new addition will sit in a position similar to the current garage. Building Relocation & Foundations: The original house will remain in its current and historic position. No changes are proposed to the original foundations except to repair any structural problems that might be found in the process. Any repairs that are made will be done in a manner to preserve the original appearance. At this time we do not anticipate any significant foundation repair to be required. Building Additions: Existing Additions: The front porch was removed and replaced with an addition to expand the front room. This project will remove the porch addition and restore an open porch as discussed above under the porch section. Page 4 of8 ~'''''''''' The entire rear bay of the house was replaced with an addition that extends the full width of the back of the house. This addition also appears to have been modified several times during its life. Due to the fact that the current siding runs continuously the full length of the structure the reading of the original form of the cross plan has been substantially obliterated by this bulky addition. The addition also sports an asymmetrical roofline, one slope of which is much shallower than that of the original house. This project will leave the rear addition in place, but proposes several superficial modifications to enhance the reading of the original house and to distinguish the addition so that it will appear more as an addition. A portion of the addition was built to look like an enclosed porch though we don't know that it ever was open. This portion of the structure will be re-sided in a different material so as to clearly distinguish it from the primary form of the original house. We also plan to add a rake to the rear of that addition that is mirror of the rake of the steeper west side pitch of the addition. This new rake will partially restore the symmetry of the rear elevation and provide a more vertical reading of the original house more consistent with the original. There mayor may not have been a rake in this position. In any case it will provide a logical point for a change of finish materials at the point where the former exterior wall clearly sat (as evidenced by the position of an old foundation wall.) '<0''''' New Addition: The most significant part of this project is the construction of a new addition in the rear of the lot. The objective of the design of the new addition is to separate it from and clearly distinguish it from the existing house. The addition consists of essentially three elements: a one-and-a-half story element, a one-story element and a Connector. The addition is intended to be "barn-like" in character and will be much more rustic than the somewhat more refined original Victorian house. The one-and-a-half story portion is pulled as far from the house as possible in order to clearly distinguish the structures as well as to help preserve light in the current rear windows of the house. The low portion will bridge most of the gap to the original structure and a glass "conservatory" structure will make the actual link to the existing building. At the same time as trying to distinguish the new addition from the existing structure, there are several aspects of the design that try to be sympathetic to the original composition and the historic development pattern. Placed at the rear of the lot, the primary form of the addition will appear as secondary structure, as is common in this area. As viewed from the street, the main portion of the addition will have a similar vertical character as the original house. In another nod to the original house the addition will include a flat projected bay window, except in this case, in a more rustic form. The primary roof form of the addition, that which faces the street, will be a simple gable similar to that of the original structure. The finishes of the addition will be rustic weathered vertical and horizontal barn wood, which will clearly distinguish it from the original house. Page 5 of8 -.,,., General Guidelines (Chapter 14): Accessibility: N/ A - this is not a public facility Color: The final color scheme has not been determined yet, however it will in principal be simple. On the original house we intend to use a single finish for the body of the clapboard siding, a single color for the shingle infill siding and a trim color. The treatment of the wood clapboard may be a natural wood finish. Currently the decorative elements have a couple of different accent colors and we have not yet determined if we will continue this or simplify the scheme slightly. The new structure will consist of a natural weathered wood finish. It will either be allowed to weather to a dark patina and sealed in a few years, or a weathered appearance finish will be applied to the natural wood. The roof of the existing house will have cedar shingles. The addition will have rusted corrugated metal roofing. Lighting: On-going Maintenance of Historic Properties: The rehabilitation of the exterior of the building will include cleaning and repainting of existing original finishes including trim boards and cut shingles. Materials requiring repair will be repaired in place where possible. Replacement will be minimized and limited to materials that are badly rotted and beyond repair. We do not anticipate a lot of replacement. Mechanical Equipment and service areas: The home does not include any exterior mechanical equipment or service areas. Driveways and Parking: The current garage is accessed from the street. This garage is being replaced by a garage that is accessed from the alley and at the location furthest from the street. An existing paved area in the street planting strip will be removed as part of this project. Signs: None ".- Page 6 of8 Aspen Residential Design Standards - Compliance memo 403 West Hallam A: Site design: 1. Building Orientation: The front facade of original house faces Hallam Street and is parallel to the street (at least almost parallel.) 2. Build to lines: The minimum front setback for this lot is 10 feet. The Front F~de of the existing historical structure is approximately 16 feet 2 3/4 inches from the front lot line or I foot 2 3/4 inches further back than specified in the guideline. The minimum side setback for this lot is 5 feet. The side facade of the existing structure is 16 feet 8 inches from the side property line or II feet 8 inches further back than specified in the guideline. We believe that this is the original position of the house and we are not proposing to move the house to meet this guideline. We propose locating the rear portion of the addition approximately 5 feet from the property line or at the minimum setback allowed for a side. The addition is not large enough to make the overall structure comply with the 60"/0 contact guideline. 3. Fences: The house currently has a looped wire fence enclosing the back yard. We propose reusing the same fence material to enclose the back yard making a slight change in the configuration to enclosed a little more of the yard. The gates will be reused. The entire fence is under the 42" limit. We propose adding a 42" solid wood fence at the alley to prevent snow from being pushed into the window well. B: Building Form: The design strategy for the addition is to make it distinctly separate from and hierarchically subordinate to, the original house. The main portion of the addition has been pulled as far as possible to the rear of the site. The connection is made by two smaller links. This emphasizes the separate identity and maximizes the amount of sunlight to fall on the back of the existing house. C: Parking, Garages and Carports: The garage is currently facing the street and there is a large parking apron. This project will reconfigure the garage to be accessed from the alley directed in the standards. The garage will be close to the grade of the alley. There will be a single bay door. Page 70f8 '. D: Building Elements: -.' I. Street orientation: The original house meets the orientation requirement. It is focused on the street of the long block. a. The original porch configuration (which we are restoring), will not meet the front door criteria, but we believe it is consistent with the intent. b. The original porch configuration was part of the front fa~ade and thus meets this criterion. c. The original structure actually has two identical "principal window(s)", one facing each of the two streets of this corner lot. The new addition will also have a "principal window" facing the side street. 2. One Story Element: The original house meets the one story element requirement. The house itself is a tall one story structure, as viewed from the front and the porch is a smaller one story element contrasting the taller portions of the house. 3. Windows: a.

Main Street- Historic Landmark Lot Split, GMQS Exemption, Demolition, Relocation and Variances- Public Hearing DATE: June 23, 2004 SUMMARY: The subject property is listed on the Aspen Inventory of Historic Landmark Sites and Structures and contains two structures, a cabin and an outbuilding. Neither building exists on the 1904 Sanborne map. The year of construction on record with the Assessor's office is 1935. HPC held a worksession on this property two months ago. The applicant wishes to receive approval to relocate the house on the site, complete restoration work to the extent possible, and make an addition to the existing cabin for use as a residential structure. A second home is to be added to the site and the outbuilding will be demolished. In order to construct this project, a variance from the minimum lot size for a Historic Landmark Lot Split will be requested, along with setback variances, and an FAR bonus. If the applicant chooses to go forward with the Conceptual design review as part of this process, variances from the "Residential Design Standards" may also be needed. The applicant has developed alternate site plans for the lot split based on HPC feedback at the worksession, and a site visit with staff. These plans were developed very close to the memo deadline and lack enough detail for a complete review, therefore the memo that follows should be considered an outline of the applicable review standards and preliminary advice to HPC. Staff recommends that the project be discussed but then continued to allow more time for research into the original appearance of the existing cabin and more finalization ofthe site plan. APPLICANT: Wes and Susan Bailey Anson, owners, represented by Jake Vickery, architect. PARCEL ID: 2735-124-46-004. ADDRESS: 701 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. I HISTORIC LANDMARK LOT SPLIT In order to complete a Historic Landmark Lot Split, the applicant shall meet the following requirements of Aspen Land Use Code: Section 26.480.030(A)(2) and (4), Section 26.470.070(C), and Section 26.415.01O(D.) 26.480.030(A)(2), SUBDIVISION EXEMPTIONS, LOT SPLIT The split of a lot for the purpose of the development of one detached single-family dwelling on a lot formed by a lot split granted subsequent to November 14, 1977, where all of the following conditions are met: a) The land is not located in a subdivision approved by either the Pitkin County Board of County Commissioners or the City Council, or the land is described as a metes and bounds parcel which has not been subdivided after the adoption of subdivision regulations by the City of Aspen on March 24, 1969. This restriction shall not apply to properties listed on the Aspen Inventory of Historic Landmark Sites and Structures; and Staff Finding: The property is part of the original townsite and has not been previously subdivided b) No more than two (2) lots are created by the lot split, both lots conform to the requirements of the underlying zone district. Any lot for which development is proposed will mitigate for affordable housing pursuant to Section 26. 100. 040(A)(I)(c). Staff Finding: The property is a non-conforming 5,765 square foot lot as a result of an adverse possession by the adjacent neighbor. This proposal will create one 3,000 square foot lot (which is the minimum size required for a Historic Landmark Lot Split), and one 2,765 square foot lot, which requires a variance that will be discussed below. Site plan alternatives are attached that divide the property par<!llel to, and perpendicular to, the orientation of the historic lot lines. Council has recently adopted new benefits for historic properties, pursuant to Section 26.420 of the Municipal Code, which states that affordable housing mitigation will not be required for properties created through a historic landmark lot split. c) The lot under consideration, or any part thereof, was not previously the subject of a subdivision exemption under the provisions of this chapter or a "lot split" exemption pursuant to Section 26.100.040(C)(I)(a); and Staff Finding: The land has not received a subdivision exemption or lot split exemption. d) A subdivision plat which meets the terms of this chapter, and conforms to the requirements of this title, is submitted and recorded in the office of the Pitkin County clerk and recorder after approval, indicating that no further subdivision 2 may be granted for these lots nor will additional units be built without receipt of applicable approvals pursuant to this chapter and growth management allocation pursuant to Chapter 26.100. Staff Finding: The subdivision plat shall be a condition of approval. It must be reviewed by the Community Development Department for approval and recordation within 180 days of final land use action. e) Recordation. The subdivision exemption agreement and plat shall be recorded in the office of the Pitkin County clerk and recorder. Failure on the part of the applicant to record the plat within one hundred eighty (180) days following approval by the City Council shall render the plat invalid and reconsideration of the plat by the City Council will be requiredfor a showing of good cause. Staff Finding: The subdivision exemption agreement shall be a condition of approval. j) In the case where an existing single:family dwelling occupies a site which is eligible for a lot split, the dwelling need not be demolished prior to application for a lot split. Staff Finding: No dwelling will be demolished as part of this lot split. The outbuilding along the alley is proposed to be demolished. It is currently being occupied as a residence illegally, which must be corrected. g) Maximum potential buildout for the two (2) parcels created by a lot split shall not exceed three (3) units, which may be composed of a duplex and a single:family home. Staff Finding: The parcel currently contains a single family home. The proposal will add one new homesite. No more than two units in total can be created as part of this redevelopment. 26.480.030(A)(4), SUBDIVISION EXEMPTIONS, HISTORIC LANDMARK LOT SPLIT The split of a lot that is listed on the Aspen Inventory of Historic Landmark Sites and Structures for the development of one new single-family dwelling may receive a subdivision exemption if it meets the following standards: a. The original parcel shall be a minimum of six thousand (6,000) square feet in size and be located in the R-6, R-15, R-15A, RMF, or 0 zone district. Staff Finding: The subject parcel is 5,765 square feet and is located in the Office Zone District. A variance is being requested in order to meet the minimum lot size stated above. 3 ^ _''''".__--..._~,~~",."..,~,._.._.,..___.,._'_..___._.~H__._ .~',... b. The total FAR for both residences shall be established by the size of the parcel and the zone district where the property is located. The total FAR for each lot shall be noted on the Subdivision Exemption Plat. Staff Finding: The maximum floor area for the original parcel, containing a historical landmark in the Office zone, is 3,142 square feet. (There is an error in the allowed floor are that is represented in the application.) The applicant will be requesting a 500 square foot FAR bonus. Clarification is needed as to how the FAR is proposed to be allocated between the parcels. Although the public notice included Conceptual design, at this time the expectation is that HPC will conduct a Major Development review to approve the architecture for the project at a future date. c. The proposed development meets all dimensional requirements of the underlying zone district. The variances provided in Section 26.415.120(B)(1)(a),(b), and (c) are only permitted on the parcels that will contain a historic structure. The FAR bonus will be added to the maximum FAR allowed on the original parcel. Staff Finding: Setback variances are requested for the parcel that will contain the cabin, but cannot be granted for the vacant new lot. VARIANCE FROM THE MINIMUM LOT SIZE REOUlREMENTS FOR A HISTORIC LANDMARK LOT SPLIT The applicant will need two variances related to lot size. The first is a variance from the minimum required size for the fathering parcel, which is 6,000 square feet. Due to the adverse possession, the lot is 5,765 square feet. The second variance is for the size of the newly created lots, which are meant to be at least 3,000 square feet each. One of the new lots will conform to the requirement, but the other will be 2,765 square feet. In order to authorize a variance from the dimensional requirements of Title 26, the HPC must make a finding that the following three (3) circumstances exist: 1. The grant of variance will be generally consistent with the purposes, goals, objectives, and policies of the Aspen Area Community Plan and this Title; Staff Finding: The AACP does support of the concept of more dense development and infill, and preservation of a variety of historic resources. 2. The grant of variance is the minimum variance that will make possible the reasonable use of the parcel, building or structure; and Staff Finding: Without the lot split, the "use by right" development options for the site are a single family house, which would entail an addition of approximately 2,400 square feet to the 675 square foot original cabin, or an office/mixed use development that would add some 3,700 square feet. HPC has found in the past the Historic Lot Split has worked well to satisfy their goals and the property owner's, and it takes away the pressure to create out of scale additions on designated buildings. Because of this, staff finds that a variance will allow for the most 4 ,-,~~-~,--",~""",---,,,-,~~""'------"""-~"-"- .. reasonable and appropriate development scenario in light of the City's Historic Preservation standards. 3. Literal interpretation and enforcement of the terms and provisions of this Title would deprive the applicant of rights commonly enjoyed by other parcels in the same zone district, and would cause the applicant unnecessary hardship or practical difficulty. In determining whether an applicant's rights would be deprived, the board shall consider whether either of the following conditions apply: a. There are special conditions and circumstances which are unique to the parcel, building or structure, which are not applicable to other parcels, structures or buildings in the same zone district and which do not resultfrom the actions of the applicant; or Staff Finding: As stated above, the property does have an unusual circumstance in that it became non-conforming through a property line dispute. The applicant is working with an existing building, which cannot be modified in any significant way. Staff finds that this standard is met. b. Granting the variance will not confer upon the applicant any special privilege denied by the Aspen Area Community Plan and the terms of this Title to other parcels, buildings, or structures, in the same zone district; and Staff Finding: No additional FAR is accrued through the variance, only the right to divide it into two residences. This is a use that is generally allowed for historic properties in the zone district. Staff finds that this review standard is met. DEMOLITION The applicant proposes to demolish the outbuilding that exists on the property and also contemplates demolition of some portion of the existing cabin if it is determined to be non- contributing. In order to approve any demolition, the HPC shall review the application, the staff report and hear evidence presented by the property owners, parties of interest and members of the general public to determine if the standards for demolition approval have been met. Demolition shall be approved if it is demonstrated that the application meets anyone of the following criteria: a. The property has been determined by the city to be an imminent hazard to public safety and the owner/applicant is unable to make the needed repairs in a timely manner, b. The structure is not structurally sound despite evidence of the owner's efforts to properly maintain the structure, c. Aspen, or The structure cannot practically be moved to another appropriate location III 5 d. No documentation exists to support or demonstrate that the property has historic, architectural, archaeological, engineering or cultural significance, and Additionally, for approval to demolish, all of the following criteria must be met: a. The structure does not contribute to the significance of the parcel or historic district in which it is located, and b. The loss of the building, structure or object would not adversely affect the integrity of the historic district or its historic, architectural or aesthetic relationship to adjacent designated properties and c. Demolition of the structure will be inconsequential to the historic preservation needs of the area. Staff Response: No information is available about the age of the outbuilding, other than that it was constructed after the 1904 Sanborne Map. A portion of it can be seen in a 1969 aerial view of the property. It appears to have been constructed in at least two phases. This is a large structure that extends almost the full width of the property along the alley. At this time, staff does not have information that would support a position that it is historically significant building. It does contribute to the alleyscape in that it is a typical one story utilitarian structure set right on the rear property line, an important development pattern in Aspen. Staff believes that without a more definitive position on the age and importance of the building, it will be burdensome to require the applicant to retain this shed. The guidelines state: /(if 1 \ rt;J"'" II I ' j IJ I I 'I . I. . \ LLJJ I 'If. I. , .J f" " I, , 11904 Map 8.1 If an existing secondary structure is historically significant, then it must be preserved. i:I When treating a historic secondary building, respect its character-defining features. These include its primary and roof materials, roof form, windows, doors and architectural details. i:I If a secondary structure is not historically significant, then its preservation is optional. 8.2 If an existing secondary structure is beyond repair, then replacing it is encouraged. i:I An exact reconstruction of the secondary structure may not be necessary in these cases. i:I The replacement should be compatible with the overall character of the historic primary structure, while accommodating new uses. With regard to the historic cabin, there is very limited information that has become available about its history, however staff has located a floor plan drawn for the assessor's office in approximately 1957 (below.) This plan supports the historical narrative provided by the applicant that suggests that an entry porch used to exist in the front portion of the building. It is 6 clear on the site that this section of the house has a different foundation. On the inside of the building there is a door opening and a window opening on what was likely the original front of the house. Staff recommends that the applicant continue to pursue other sources to guide the rehabilitation of this cabin, including older assessor records that may be available at the Aspen Historical Society, photographs of Main Street at the Historical Society, and any photographs that neighbors or other Aspen residents may have. It is very important to locate more facts about the building in order to go forward with this project as a preservation effort that is worthy of receiving variances. 11957 Floor ON-SITE RELOCATION 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. 26.415.090.C Standards for the Relocation of Designated Properties Relocation for a building, structure or object will be approved if it is determined that it meets anyone ofthe 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; .!!! 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; or 3. The owner has obtained a Certificate of Economic Hardship; .!!! 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 Additionallv, for approval to relocate all ofthe followinl!: 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: At the worksession there was debate about whether it is appropriate to divide this property so that the front lot is cut off from the alley. The applicant has restudied the idea 7 -,-.,~._._,.._--~._--.~' and provided HPC with alternative plans. In either case the cabin is proposed to be moved to the side and forward of its current location. "Option A" indicates the front and rear portions of the building being removed, which mayor may not prove to be appropriate based on additional research. "Option B" retains the whole structure and places it fairly close to the front property line. "Option C" is the typical, and generally preferred lot split layout, although the architect has chosen to place the cabin on the interior lot, which needs to be discussed. There is a large spruce tree at the front of the site that significantly influences all of the options. The following guideline will be in question: 9.1 Proposals to relocate a building will be considered on a case-by-case basis. i:I In general, relocation has less of an impact on individual landmark structures than those in a historic district. i:I It must be demonstrated that relocation is the best preservation alternative. i:I Rehabilitation of a historic building must occur as a first phase of any improvements. i:I A relocated building must be carefully rehabilitated to retain original architectural details and materials. i:I 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. i:I The design of a new structure on the site should be in accordance with the guidelines for new construction. i:I In general, moving a building to an entirely different site or neighborhood is not approved. HPC should also review all of the guidelines in Exhibit B, which are important to the issue of the site plan. Original location is an aspect of the property that helps to define historic integrity. Relocation of the building can be justified when it allows breathing room for an appropriately designed addition. FAR BONUS The applicant is requesting a 500 square foot floor area bonus. The following standards apply to an FAR bonus, per Section 26.415.IIO.E: 1. In selected circumstances the HPC may grant up to five hundred (500) additional square feet of allowable floor area for projects involving designated historic properties. To be considered for the bonus, it must be demonstrated that: a. The design of the project meets all applicable design guidelines; and b. The historic building is the key element of the property and the addition is incorporated in a manner that maintains the visual integrity of the historic building and/or c. The work restores the existing portion of the building to its historic appearance; and/or d. The new construction is reflective of the proportional patterns found in the historic building's form, materials or openings; and/or e. The construction materials are of the highest quality; and/or f. An appropriate transition defines the old and new portions of the building; and/or 8 g. The project retains a historic outbuilding; and/or h. Notable historic site and landscape features are retained. 2. Granting of additional allowable floor area is not a matter of right but is contingent upon the sole discretion of the HPC and the Commission's assessments of the merits ofthe proposed project and its ability to demonstrate exemplary historic preservation practices. Projects that demonstrate multiple elements described above will have a greater likelihood of being awarded additional floor area. 3. The decision to grant a Floor Area Bonus for Major Development projects will occur as part of the approval of a Conceptual Development Plan, pursuant to Section 26.415.070(D). No development application that includes a request for a Floor Area Bonus may be submitted until after the applicant has met with the HPC in a work session to discuss how the proposal might meet the bonus considerations. Staff Response: Additional research and discussion is needed before any finding on the FAR bonus is possible. A bonus will not be appropriate if the project is based solely on guesswork about the cabin's original appearance. SETBACK VARIANCES The setback variances needed are not defined at this time since the site plan is a work in progress. The criteria, per Section 26.415.110.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; and/or 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: No findings can be made at this time. 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. 9 . ~~._~<."~_.-..>'-<-- RECOMMENDATION: Staff recommends that HPC provide some feedback based on the information before them and then continue the hearing to a date certain, which will be July 28th or later. Exhibits: A. Staff memo dated June 23, 2004 B. Relevant Design Guidelines 10 "Exhibit B: Relevant Design Guidelines for 701 W. Main Street Historic Landmark Lot Split, Demolition, Relocation and Variances" 1.11 Preserve and maintain mature landscaping on site, particularly landmark trees and shrubs. i:I Protect established vegetation during construction to avoid damage. Replacement of damaged, aged or diseased trees must be approved by the Parks Department. i:I If a tree must be removed as part of the addition or alteration, replace it with species of a large enough scale to have a visual impact in the early years of the project. 8.1 If an existing secondary structure is historically significant, then it must be preserved. i:I When treating a historic secondary building, respect its character-defining features. These include its primary and roof materials, roof form, windows, doors and architectural details. i:I If a secondary structure is not historically significant, then its preservation is optional. 8.2 If an existing secondary structure is beyond repair, then replacing it is encouraged. i:I An exact reconstruction of the secondary structure may not be necessary in these cases. i:I The replacement should be compatible with the overall character of the historic primary structure, while accommodating new uses. 9.1 Proposals to relocate a building will be considered on a case-by-case basis. i:lln general, relocation has less of an impact on individual landmark structures than those in a historic district. i:I It must be demonstrated that relocation is the best preservation alternative. i:I Rehabilitation of a historic building must occur as a first phase of any improvements. i:I A relocated building must be carefully rehabilitated to retain original architectural details and materials. i:I 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. i:I The design of a new structure on the site should be in accordance with the guidelines for new construction. i:I 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. i:I The significance of a building and the character of its setting will be considered. i:I 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. i:I 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. 11 9.4 Site the structure in a position similar to its historic orientation. i:I It should face the same direction and have a relatively similar setback. i:I It may not, for example, be moved to the rear of the parcel to accommodate a new building in front of it. 10.1 Preserve an older addition that has achieved historic significance in its own right. i:I Such an addition is usually similar in character to the original building in terms of materials, finishes and design. 10.2 A more recent addition that is not historically significant may be removed. 11.1 Orient the primary entrance of a new building to the street. (New buildings on Landmark Lot Splits) i:I The building should be arranged parallel to the lot lines, maintaining the traditional grid pattern of the site. 12.1 Respect historic settlement patterns. (Main Street Historic District) i:I 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. 12.6 Minimize the use of curb cuts along the street. (MSHD) i:I Provide auto access along an alley when feasible. i:I New curb cuts are not permitted. i:I Whenever possible, remove an existing curb cut. 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) i:I The building should be oriented parallel to the lot lines, maintaining the traditional grid pattern of the block. i:I 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. 12.10 12.10 When constructing a new building, locate it to fit within the range of yard dimensions seen in the block. (MSHD) i:I These include front yard, side yard and rear yard setbacks. i:I In some areas, setbacks vary, but generally fall within an established range. A greater variety in setbacks is inappropriate in this context. i:I Consider locating within the average range of setbacks along the block. 12.11 Keep the front setback of a new structure in line with the range of setbacks on the block seen historically during the mining era. (MSHD) 12 ~-....... 12.12Maintain similar side yard setbacks of a new structure or an addition to those seen traditionally in the block during the mining era. 14.17 Design a new driveway in a manner that minimizes its visual impact. i:I Plan parking areas and driveways in a manner that utilizes existing curb cuts. New curb cuts are not permitted. i:I If an alley exists, a new driveway must be located off of it. 14.18 Garages should not dominate the street scene.
