BACKGROUND:
202 East Main Street is a designated landmark on a 3,000 square foot lot in the MU zone district. This
property contains a one-story miner’s cottage with a non-historic addition to the rear of the property.
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”.

In 2012, Aspen City Council granted approval for a Historic Lot Split between 202 E. Main and 208 E.
Main creating two (2) 3,000 sf parcels (Ordinance #14, Series of 2012). The Historic Preservation
Commission (HPC) granted approvals for demolition of a storage room that linked the two historic
structures together and setback variations for both parcels (Resolution #5, Series of 2012).
NOTE:
This project will be reviewed under the Land Use Code prior to the 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.
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
construction of a new addition towards the rear of the historic building.
• Relocation (Section 26.415.090) for the relocation of the historic residence onto a new basement.
• Setback Variation (Section 26.415.110.C) for the new addition, lightwells, and trash enclosure.

130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com
• Parking Reduction and Waiver of fees (Section 26.415.110.D) request for a reduction of one (1)
parking space and fee waivers.
• Floor Area Bonus (Section 26.415.110.F) request for a 500 sf bonus for the rooftop deck and
lightwells.
The HPC is the final review authority, however, this project is subject to Call-up Notice to City Council.
The project, once approved, will be granted an Administrative Growth Management Exemption for
Change in Use from commercial to residential with no affordable housing mitigation required.
PROJECT SUMMARY:
The applicant proposes to demolish the existing non-historic addition and construct a new above grade
addition to the rear of the historic resource. A full basement is proposed and will require the temporary
relocation of the historic structure during excavation. The proposed design changes the use from
commercial to a single-family residence, which results in a 20% floor area reduction as required by
underlying zoning. The applicant requests setback variations, parking reduction, fee waivers, and a floor
area bonus of 500 sf as part of this proposal.
STAFF COMMENTS:
The applicant highlights the importance of site context and proposes to maintain the historic alignment
of the historic structure with the adjacent properties, which is in compliance with Guideline 1.1. The
applicant plans to pursue preservation/restoration work on the historic resource according to the
Historic Preservation Design Guidelines, but staff finds that the proposed new above grade addition
does not meet the Design Guidelines and recommends continuation. The new addition must achieve
compatibility with the historic landmark according to Design Guideline 10.6. As part of the restudy, staff
requests a preliminary stormwater mitigation plan that takes the proposed design and existing site
conditions into account.
The following points go into more detail regarding the proposal for HPC discussion:
1. Site Planning & Relocation: The Sanborn maps indicate the existing footprint of the historic
house is original to the location. To construct the basement design, the applicant plans to
temporarily move the house on site, then onto the new foundation. Ultimately, the historic
structure will be placed back in its original location. The applicant will need to provide structural
assessment and financial assurances in order to comply with Design Guideline 9.1.
Considering the lot size, the proposed subgrade addition, and the large Cottonwood trees near
the property, staff finds preliminary plans addressing stormwater mitigation is critical. As part of
the site design, Historic Preservation Guideline 1.8 recommends stormwater management be
addressed early in the design process. Other City Departments have provided comments
Page 4 of 10
130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com
requesting more information and discussion about plans for stormwater mitigation and
identifying locations for a new waterline. See referral comments for details (Exhibit B).
As part of the site planning process, the applicant will need to work closely with relevant City
Departments to address allowed work in the dripline of trees and requirements related to public
improvement. Staff supports the removal of the small spruce tree in the front yard of the historic
property due to its proximity to the resource. Additionally, the final grading of the site will need
to maintain the historic relationship of how the structure meets the ground while providing
positive drainage (Design Guideline 1.8).
In order to provide natural light into the subgrade spaces, the applicant proposes two large
lightwells. One is located between the historic resource and the new addition on the west side
of the property and the other one is abutting the historic porch along the street facing façade of
the historic building. Staff finds that the street facing lightwell adjacent to the historic porch
does not meet Design Guideline 9.6 and recommends restudy.
Figure 3 – Proposed Site Plan
Staff finds the criteria for relocation are met, but more information needs to be provided in order
to address the comments and concerns expressed by other City Departments related to excavation
staying within the property boundaries. Staff requests preliminary stormwater mitigation plans for
the proposed design due to the design of the subgrade space and the existing site conditions. Staff
recommends restudy of the proposed front lightwell.
2. New Addition – Connecting Element & Form/Materials/Fenestration: The proposed above
grade addition is taller than the historic building and has a floor area that is approximately 87 sf
larger than the historic resource. The transitional space between the old and the new is a two-
Page 5 of 10
130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com
story space that contains vertical circulation. A majority of the roof form on the new addition is
a flat roof with a roof deck and an 8:12 pitched roof above the master bedroom along the alley.
Connecting Element: When a new addition is taller than the historic resource, the guidelines
call for a one-story connector with a minimum length of 10 feet that tucks under the eave of the
historic building in order to provide a meaningful separation (Guideline 10.9). The proposed
connection does not meet this guideline. The size of the lot and the surrounding context does
create a limited area for new development, but the current design of the new addition does not
create a sensitive transition between the old and new.
According to Design Guideline 10.6, the new addition needs to be recognized as a product of its
own time, but visual compatibility with the historic resource must be achieved. In order to
promote compatibility, the Design Guidelines requires two of the following characteristics to
relate back to the historic resource: form, material and fenestration.

Figure 5 – Proposed West Elevation

130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com
Form: The overall form of the above grade addition is a composition of articulated rectilinear
shapes expressed through material changes and minor changes in plane. Much of the addition
has a flat roof. A small portion of the upper level towards the alley with a 8:12 pitched roof. When
compared to the cross gabled historic resource, the form and massing of the addition does not
strongly relate to the forms found on the historic resource.
Materials: The historic miner’s cottage is mostly clad with horizontal clapboard siding and
decorative architectural detailing on the front façade and porch. The historic structure sits on a
simple brick foundation. The new above grade addition is a combination of stone or tile and
metal siding. The variety of materials and different application method result in accentuating
individual massing elements of the new addition, which is a stark contrast from the uniformity
created by the historic wood siding on the historic resource. It is clear there is a deliberate
departure from materials in this design.
Fenestration: The fenestration choices on the new addition are elongated window openings in
both vertical and horizontal configurations. The fenestration on the historic resource consists of
mostly double hung windows. The design does allude to the historic window proportions;
however, due to the various window orientations found on the new addition, it is difficult to
identify a direct correlation between the old and new fenestration.
The Design Guidelines call for visual compatibility between the new addition and the historic
landmark. Staff finds that the proposed design of the above grade new addition deviates from
all three categories of form, materials, and fenestration. Staff recommends restudy of the
design by picking two of the three characteristics in order to create visual compatibility. Staff
recommends restudy of the connecting element to comply with Guideline 10.9 since the new
addition is taller than the historic resource.
3. Dimensional Variations: As a historically designated landmark, certain preservation benefits
may be granted by HPC. As mentioned above, this application was submitted and deemed
complete before the code amendments to the Historic Preservation Benefits went into effect,
therefore, is subject to the old code.
Setback Variations:
Following the Historic Lot Split between 202 E. Main and 208 E. Main, HPC granted the following
setback variations for the historic resource (Resolution #5, Series of 2012):
• up to a 5’ west sideyard setback reduction for the existing main building
• 2’ setback east sideyard setback reduction for the existing main building
• 5’ rear yard setback reduction for an existing roof over the rear entry path
With this project, the applicant requests additional setback variations for the project:
• 2’ setback west sideyard setback reduction for new addition
• 2’ setback east sideyard setback reduction for new addition
Page 7 of 10
130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com
In granting a variance, the HPC must make a finding that such a 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.
Parking Reductions & Fee Waivers:
Underlying zoning requires two (2) parking spaces for single-family residence. Due to the site
configuration and the location of the historic resource, the applicant proposes one (1) on-site
parking spot accessed from the alley and requests a parking reduction of one (1) space. Access
for the proposed one car garage is off the alley.
According to Section 26.415.110.D, HPC may approve the reduction of parking upon a finding that
it will enhance or mitigate an adverse impact on the historic significance or architectural
character of a designed historic property. As a designated property under the old code,
exemptions for growth management and impact fees are available.
Staff recognizes the potential challenges for providing two on-site parking spaces on this site
due to the lot size and the need to maintain the historic alignment of the front façade, but
recommends restudy of the proposed rear addition to provide a more sensitive connection
between the old and new. Following this restudy, staff would like to reevaluate the possibility of
providing two (2) on-site parking spaces.
Staff supports the request for setback variations since it is a result of maintaining the historic
location of the historic house which enhances the historic significance of the property. Staff
recommends restudy of the current design for the new addition in order to reevaluate the impact
of providing two (2) on-site parking spaces to the historic resource.
4. Floor Area Bonus: The applicant is requesting a floor area bonus to the amount of 500 sf. The
proposal mentions undertaking any necessary restoration/preservation work and indicates that
the extra floor area is for the proposed rooftop deck and lightwells. The proposed use of
additional floor area would not increase mass and scale. Following is the criteria for awarding a
floor area bonus for this application (Section 415.110.F)
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:
Page 8 of 10
130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com
a) The design of the project meets all applicable design guidelines;
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;
c) The work restores the existing portion of the building to its historic appearance;
d) The new construction is reflective of the proportional patterns found in the historic building's
form, materials or openings;
e) The construction materials are of the highest quality;
f) An appropriate transition defines the old and new portions of the building;
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.
Staff recognizes that with the change in use from commercial to residential, the property is subject to a
considerable floor area reduction. A single family home is limited to 1,920 sf, whereas a commercial
property could be 3,000 sf. There is, however, a challenge in accommodating significant expansion on
this site in a sympathetic manner.
Staff finds that a number of criteria for a floor area bonus are being met; however, the proposed
design of the new addition does not meet all applicable Design Guidelines. Staff recommends
restudy of the new addition before awarding any amount of a floor area.
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 more
details.
Engineering Department:
1. The applicant will need to provide a conceptual level information regarding stormwater
treatment and how onsite runoff will be captured and treated prior to HPC approval.
