Main 202 Page 2 of 6 130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com BACKGROUND: 202 East Main Street is a designated landmark 3,000 square foot lot in the Mixed-Use zone district. This property contains a one-story miner’s cottage with a non-historic addition to the rear. The house appears to be in its original location according to the historic Sanborn maps. Historic photographs show that much of the original architectural details are intact. There is a small spruce tree in front of the historic resource and two large cottonwood trees towards the front of the property in the public right-of-way. The site slopes down towards the alley by approximately 3’-6”. REQUEST OF HISTORIC PRESERVATION COMMISSION (HPC) The Applicant is requesting the following land use approvals: • Major Development (Section 26.415.070.D) for the demolition of the non-historic addition and the construction of a new addition to the rear of the property. • Setback Variations (Section 26.415.110.C) for the historic home to remain in its current location and the proposed new addition. This Conceptual approval granted for this project was not called up by City Council during the Notice of Call-up held on December 10, 2019. Conceptual approval is valid for one year. The applicant was granted a six month extension of their Conceptual Development approval by HPC, and a complete Final Development application was received prior to the deadline. HPC is the final review authority for Final Design Development Review. NOTE: This project is reviewed under the Land Use Code prior to the historic preservation benefits code amendments approved by City Council on May 13, 2019 because it was submitted and declared complete before the new code language went into effect on June 12, 2019.

Main, 1890 Source: Aspen Historical Society Page 3 of 6 130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com PROJECT SUMMARY: The applicant received Conceptual approval to restore architectural elements of the historic home, demolish the non-historic addition, and relocate the historic home on a new basement foundation. The mass and scale of the new addition was approved and HPC granted setback variations and a floor area bonus of 500 s.f. for the approved design. Since Conceptual approval, the property was sold to a new owner. The Final review includes minor revisions that stay within the parameters of Conceptual approval and corrections to the setback variations. This Final application addresses building materials and fenestration selection, design modifications to address constructability, landscape plan, lighting plan and mechanical equipment. STAFF COMMENTS: Staff supports the submitted application for Final Design Review but recommends HPC further discuss the following topics. 1. Landscape Plan & Stormwater Mitigation Plan: The proposed landscape plan incorporates a maintenance edge around the foundation of the historic home. The existing spruce tree in the front yard is to be removed and a 3’ wide concrete front walkway is proposed. After further investigation, it has been identified that the cottonwood tree in the right of way needs to be removed. The applicant shall continue discussions with the Parks Department related to the removal of this tree and appropriate mitigation requirements. Open space on the property is concentrated towards the front yard of the property. The proposed diagonal configuration of perennials plantings in the most significant zone is out of character with the historic resource. Additionally, the proposed dogwoods around the southwest corner of the historic home and along the front porch are too close to the resource and too dense. Staff recommends the front yard maintain existing sod conditions and the restudy of the perennial beds and plantings in the front yard to meet Design Guidelines 1.12 and 1.13. The metal fence proposed along the front yard is a reconstruction of a historic fence using photographic evidence which meets Design Guideline 1.16. A new concrete site wall is proposed to replace the stone retaining wall that is failing along the southwest side corner of the property. The applicant indicates that this stone wall is not historic. While concrete would be an appropriate material, staff recommends the height of this feature be reduced to the minimum required to meet Design Guideline 1.22. The stormwater mitigation plan seems to rely on the rain garden configurations on the site. With staff’s recommendation to restudy the front yard perennial beds, changes to the stormwater mitigation plan may be required. The final design needs to limit visual impacts to the foreground of the resource to meet Design Guideline 1.8. 2. Historic Landmark – Alterations: The applicant proposes the restoration of architectural details that include historic fenestration, the historic brick chimney, and other architectural details. The preservation approach must be reviewed by staff prior to building permit to confirm that the front doors and transoms to be preserved are original (if not, restoration is needed) Page 4 of 6 130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com and to ensure that the chimney is reconstructed to accurate dimensions.) As part of this review, the applicant requests the installation of a new skylight on the historic resource behind the main gable. Although this feature would not be visible from Main Street, staff finds this alteration does not support restoration efforts and such features are typically not allowed on the historic resource (Design Guideline 7.3). A black surface mounted light fixture is proposed in the soffit of the front porch. Although the fixture is simple in design, a recessed fixture would be more appropriate for this location (Design Guideline 12.3). 3. New Addition – Materials & Fenestration & Mechanical Equipment: The approved two- story addition is located to the rear of the property with a one-story connecting element that tucks under the eaves of the historic building. The length of the connecting element has been modified to be slightly longer than what was previously proposed, and the garage and alley- facing loggia has been revised to accommodate the dimensions of two on-site parking spaces (please note that the required width of a parking space is 8’6” and the plans need to be clarified to confirm that is provided for each space in the garage). The proposed lightwell in the southwest corner of the property has been revised for constructability and is now less visible from the street (Design Guideline 9.6). Staff supports the modifications made for Final review because they address constructability concerns while maintaining the overall mass and scale of the conceptual approval. Materials & Fenestration: The approved addition relates to the historic resource using building materials and fenestration, while departing from form. Wood siding is called out as the main cladding material for the new addition. Although the butt-jointed installation of the siding on the new construction is a contemporary approach, the dimensions of the siding relates to the exposure of the historic clapboard siding. The proposed fenestration in the Final application reduces the overall amount of glazing from what was previously proposed for the addition and the fenestration dimensions strongly relate to the dimensions of the historic double-hung windows. Staff finds the final building materials and fenestration achieve a strong design compatibility with the historic resource and meet Design Guideline 10.6. Mechanical Equipment: The applicant proposes three condensing units directly mounted to the new addition on the east elevation. According to Design Guideline 12.4, mechanical equipment may only be mounted on the building on an alley façade. Staff recommends the proposed equipment be located on the ground where it can be screened (Design Guideline 12.4). The proposed location also appears to be problematic because they intrude into the side yard setback and were not part of what was evaluated for a variation at Conceptual and they may not be able to meet the limitations on noise levels that are acceptable as measured from a property line. A revised plan for this equipment is needed. 4. Setback Variations: Setback variations were granted to the project during conceptual review for the purposes of memorializing the location of the historic resource on the site and the location of the new addition as it relates to the resource. The applicant has identified an error Page 5 of 6 130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com in the recorded language regarding the setback variations granted during Conceptual review and requests the following setback variations which will fix the error: • 5’ setback reduction of the west side yard, above and below grade, for the historic house, the lightwell, the new addition, and the trash enclosure. • 2’ setback reduction of the east side yard, above and below grade, for the historic house, the proposed lightwell, and the new addition. • 5’ setback reduction of the rear yard setback for the trash enclosure. REFERRAL COMMENTS: The application was referred out to other City Departments who have requirements that will significantly affect the permit review. The following is a summary of comments received. See Exhibit C for details. Engineering Department: 1. At the time of building permit, an agreement with the neighbor to the west of the property is needed before redoing their existing sidewalk. 2. At the time of building permit, finalize details regarding the service line minimum dimensions required for the property. 3. At the time of building permit, address details related to the water service line associated with both 202 E. Main and 208 E. Main. 4. At the time of building permit, address and finalize stormwater comments. Parks Department: 1. A tree permit will be required for the request to remove two trees. A cottonwood tree needs to be planted back in the right-of-way. 2. Additional discussion is needed about repair of the existing water line that services both 202 E. Main and 208 E. Main. RECOMMENDATION: Staff recommends the Historic Preservation Commission (HPC) approve this application with the following conditions: 1.) Restudy the landscape plan for the front yard to maintain traditional sod and perennial conditions and reduce plantings surrounding the front of the historic resource to meet Design Guidelines 1.12 and 1.13. The final landscape plan to be reviewed and approved by staff and monitor prior to building permit submission. 2.) Continue to work with all relevant City Departments regarding the stormwater mitigation plan. Stormwater features shall not create visual impact to the historic resource. Any changes to be reviewed and approved by staff and monitor prior to building permit submission. Page 6 of 6 130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com 3.) The preservation approach on the historic resource must be reviewed by staff prior to building permit to confirm that the front doors and transoms to be preserved are original (if not, restoration is needed) and to ensure that the chimney is reconstructed to accurate dimensions.) 4.) Remove the proposed skylight in the historic resource. 5.) Replace the surface mounted light fixture with a recessed fixture in the soffit of the front porch. 6.) Propose a new plan for the proposed condensing units to meet setback and noise requirements, and screen the units to meet Design Guideline 12.4. 7.) Provide cutsheets for gutters, downspouts, and snow clips, to be reviewed and approved by staff and monitor prior to building permit submission. 8.) The visual impact of the location of the fire department connection (FDC) hook-up and strobe must be reviewed and approved by staff and monitor prior to building permit submission. 9.) The following setback variations are granted for this project: • 5’ setback reduction of the west side yard, above and below grade, for the historic house, the lightwell, the new addition, and the trash enclosure. • 2’ setback reduction of the east side yard, above and below grade, for the historic house, the proposed lightwell, and the new addition. • 5’ setback reduction of the rear yard setback for the trash enclosure. 10.) Conceptual approval included a 500 square foot bonus, but the Final application represents that only 412 square feet is needed. All calculations will be confirmed during building permit review. Bonus floor area not used for this project will be forfeited and must be earned through a future request.
