Francis Street 234 Page 2 of 7 130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com BACKGROUND: 234 West Francis Street is a locally designated landmark and listed on the National Register of Historic Places. The 1904 Sanborn Map confirms the current lot includes two historic properties which have since merged into a single 9,000 sf lot in the R-6 zone district. This property contains a two-story Victorian home and a one-story miner’s cabin. The 2000 Historic Inventory Form describes the historic property as lots K, L and M with descriptions of the one-story miner’s cabin as an associated building. In addition to its architectural significance, the property is associated with significant figures such as Judge Davis Waite, and later Herbert Bayer. Figure 1 - Sanborn Map,1904 Figure 2 - 234 W. Francis, 2019 REQUEST OF HISTORIC PRESERVATION COMMISSION (HPC) The Applicant is requesting the following land use approvals: • Major Development (Section 26.415.070.D) for demolition of non-historic additions and the construction of a new addition to the rear of the historic property. • Relocation (Section 26.415.090) to underpin the historic resources to excavate the basement. • Setback Variation (Section 26.415.110.C) to memorialize the historic structures in their current historic location. This project was not called up by City Council during the Notice of Call-up on March 10th, 2020. HPC is the final review authority for Final Design Development Review. PROJECT SUMMARY: The applicant received Conceptual approval to demolish the existing non-historic addition directly behind the two-story Victorian home and construct a new addition. As part of this scope, the design addresses the enlarged and connected the existing basements. HPC granted setback variations at Conceptual review and awarded a 472 square foot floor area bonus for restoration work to occur on both historic structures. Page 3 of 7 130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com This submission for Final Review is consistent with the Conceptual approval, but includes minor adjustments, such as a 6” increase to the height of the proposed addition. The height increase is due to constructability and does not create any non-conformities, nor does the addition become taller than the main historic home. The Final review also amends the previous scope for Relocation and Setback Variations related to the underpinning of the historic resources in order to excavate a slightly deeper basement. Both historic resources will remain in their historic location. The application includes a response to a condition of approval regarding the roof over a west facing entry into the home. Staff finds the modified overhang feature located above the secondary entrance addresses the concerns expressed by HPC during the Conceptual review in that the feature is now detached from the historic resource and scaled down. In the process of preparing this application, the applicant determined that it would be appropriate to remove a non-historic brick chimney on the east side of the one-story historic structure as it currently encroaches into the neighbor’s property. The applicant proposes to demolish this feature and replace it with a lead-coated copper chimney flue. STAFF COMMENTS: Staff supports the revised design of the new addition and the request for Relocation and Setback Variations. Staff recommends HPC further discuss the proposed landscape and lighting plan for compliance. The following points go into more detail regarding the proposal for HPC discussion: 1. Landscape/Site Plan & Relocation: The approved footprint of the new addition is concentrated to the rear of the property and positive open space is maintained around the historic structures. A sunken patio space is proposed at the center of the site, recessed from Francis Street. A built-in hot tub is also in this area and is screened by the surrounding structures and does not obscure the historic resources (Design Guideline 1.10). The proposed landscape plan incorporates a gravel maintenance edge around the historic buildings to help protect the foundations, and large trees on site will be protected and preserved as directed by the Parks Department. New shrubs are appropriately distanced from the resources, but extensive perennial beds are proposed around the two-story historic home where there is sod currently. Staff recommends HPC discuss the proposed landscaping plans and its compliance to Design Guideline 1.12. The proposed secondary pathway leading to the entrance facing 2nd Street starts at the same width as the front walkway with planted joints between the stones to differentiate its presence as the secondary pathway, but behind the Bayer fence and gate the pathway expands in width from 3’- 6” to 9’-1”. Although the expansion of the secondary pathway occurs past the gate, this pathway reads as a primary feature. Staff recommends reducing Page 4 of 7 130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com the scale, width, and presence of the secondary pathway to meet Design Guidelines 4.1 and 10.4. Relocation review is triggered because both historic structures will need to be underpinned in order to enlarge the basement. Approval to excavate and enlarge the basement was given during Conceptual Review but requires amendment because areas of the basement are excavated to a lower depth than existing. Staff recommends HPC further discuss the proposed landscape plan for adding perennials around the main historic house. Staff finds the proposed secondary pathway competes with the primary entrance and recommends the feature be reduced further in width and scale to meet the relevant Historic Preservation Design Guidelines. 2. New Addition: The proposed addition to the historic landmark relates strongly to the resources in form and materials (Design Guideline 10.3 and 10.6). The 6 inch increase in height for the two-story addition since Conceptual approval is related to the constructability of the structure. Staff finds that this change does not impact the overall scale and design of the addition. Form: The proposed addition consists of a combination of a gable roof that strongly relates to the two historic structures, and flat roofs the ensure visual porosity. (Design Guideline 1.7, 10.8 and 10.10). The flat roof with the parapet also creates an appropriate location to install solar panels on the property. Materials: Horizontal wood siding and cedar shingles are the primary materials found on the historic structures. Architectural details include fishscale shingles, turned wooden posts and simple wood trim details. The cladding material proposed for the new addition is 3” wide horizontal wood cladding and a metal roof. The metal roof material does not directly relate to the historic roofing material of cedar wood shingles, however, in this case a large majority of the visible material is wood siding. Fenestration: The proposed design purposefully deviates from fenestration. The south elevation viewed from Francis Street show large areas of glazing that opens into the sunken patio area. The west elevation contains the secondary entry next to a large fixed picture window. Parking: In addition to compliance with the design guidelines, the project must adhere to R-6 dimensional requirements. The property must have two on-site parking spaces, at least 8 ½’ wide by 18’ deep. The floor plans indicate a raised platform and step in the center of the garage that would prohibit parking two cars. The plan must be revised for building permit review.

Staff requests a revised plan showing the provision of two on-site parking space prior to building permit submission. 3. Setback Variations: Setback variations granted by HPC are site-specific approvals granted to specific features represented in the application. The requested setback variations for Final Review are for the two historic resources to remain in their current location. In granting a variation, the HPC must make a finding that such a variation: 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. The following setback variations are needed to memorialize the historic structures in the setbacks because relocation was triggered: • 10’ east side yard setback reduction for the one-story historic structure, above and below grade. • Approximately 2’-7” west side yard setback reduction as represented in the site plan drawings for the two-story historic structure, above and below grade. Staff supports the request for setback variations since they meet all criteria and benefit the historic resources.
