Cooper Avenue 820 Page 2 of 4 130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com BACKGROUND: 820 East Cooper is a 3,000 sf lot in the RMF zone district. The historic resource is a one- story miner’s cabin with a loft. In 1996 HPC approved a new addition to the historic structure that was never built. In 2012, HPC granted the demolition of a non- historic shed structure along the alley. The property was recently acquired by the current applicant who has been working with staff to remove the non-historic wrap around deck that covered the base of the historic resource, restore the historic windows, and remove the blue metal roof and replace it with the asphalt shingle roof. REQUEST OF HISTORIC PRESERVATION COMMISSION (HPC): The Applicant is requesting the following approval: • Minor Development (Section 26.415.070.C) o add a small addition to the rear, restore historic features and make landscaping changes. The Historic Preservation Commission (HPC) is the final review authority. The scope of this application is not subject to Notice of Call-Up at City Council. PROJECT SUMMARY: The applicant proposes to enlarge an existing non-historic addition to the rear of the historic structure by adding approximately 46 sf of floor area. As part of the scope of work, the altered front door of the historic resource will be restored to historic proportions and landscaping changes including pervious brick pavers and tree removal are proposed. No historic preservation benefits or incentives are requested for this proposal. STAFF COMMENTS: The proposed addition to the rear of the property is an enlargement of a non-historic addition that improves the usability of this space without compromising the historic fabric and having minimal visual impact. The proposed addition utilizes a pitched roof form the relates to the historic resource and fenestration with dimensions that keep in character with the historic resource. The proposed material is asphalt shingles, matching what is in place on the historic resource, and a vertical application of Trespa siding which deviates from the historic resource. Staff finds that all relevant Design Guidelines in Chapter 10 are met. Staff supports the proposed addition and restoration plan of the historic front door opening using historic photographs and the existing framing as a reference. (See Figure 2.) Figure 1 – 820 E. Cooper, 2020 Page 3 of 4 130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com Staff recommends HPC further discuss elements of the proposed landscape plan in detail to provide more direction for the applicant: Landscaping Changes: Following the removal of the wooden deck that wrapped around the entire footprint of the building, the applicant proposes to stabilize the surrounding grade with various landscaping improvements including the use of permeable brick pavers, sod, and perennial beds. The permeable brick pavers will be used to create a perpendicular walkway from the street to the front door of the historic resource which meets Design Guideline 1.6; however, staff finds the pavers proposed along the foundation of the front façade to be out of character and does not meet Design Guideline 1.12. Staff recommends the pavers be limited to the walkway and entry leading up to the front door and either sod or plantings along the front façade. Any proposed plantings must not cover or screen the historic resource from view. No changes are proposed to the existing fence with this proposal. The applicant proposes to restore sod in front of the historic resource and maintain the sod located towards the rear of the property. The gravel areas identified along the rear of the property appears to be associated with the two on-site parking spaces required for the property that must remain. The applicant is currently working with the Parks Department on the removal of the tree located in the front yard of the property. Staff recommends the applicant continue discussion with all relevant City Departments regarding tree impact/mitigation and stormwater needs for the site. REFERRAL COMMENTS: The application was referred out to other City Departments who have requirements that will significantly affect the permit review. Please see Exhibit B for full comments. Engineering Department: 1. Applicant needs to show the disturbance area is under 1,000 sf or provide a full drainage plan and report from a registered engineer.
