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. 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 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.
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 proposed design including the new addition and
lightwells.

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 waiver.
• Floor Area Bonus (Section 26.415.110.F) request for a 500 sf bonus.
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.
Following the August 28, 2019 continuation by HPC the applicant has revised the proposed design for the
connecting element and the above grade addition. The revised connecting element is 5’ in length and
one-story. The proposed addition relates to the historic resource through building materials and
fenestration but deviates in form. A flat roof with a rooftop deck and a green roof is proposed. The revised
design proposes a new dormer to the rear of the historic resource that lines up with the existing historic
cross gable.
STAFF COMMENTS:
Staff finds that the revised proposal addresses concerns regarding the connecting element and design
compatibility of the proposed addition as it relates to the historic resource. The revised design proposes
new fenestration that gestures to the size and proportion of the historic fenestration and utilizes materials
are similar to the historic resource. The proposed connecting element is one-story, tucks under the eave
of the historic resource and provides a 5’ distance between the historic resource and the proposed new
addition. Staff continues to support the applicant’s plan to maintain the historic alignment along Main
Street and the plan to pursue preservation/restoration work on the historic resource. Staff recognizes the
site constraints presented on this lot due to maintaining this alignment and preserving the large
cottonwood trees. Staff supports the request for setback variations with the revised design. Staff
supports the applicant’s request for a floor area bonus because it meets the criteria for a bonus.
The following points go into more detail regarding the revised proposal for HPC discussion:
1. Site Planning & Relocation: The Sanborn maps indicate the historic house is in its original 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.

130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com
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. The applicant
has reached out to the relevant City Departments to discuss feasible options to address
stormwater mitigation on the site. As part of the solution, a green roof is being proposed on the
new addition. The applicant will need to continue working closely with relevant City Departments
and staff and monitor for any future design changes.
Staff supports the removal of the spruce tree in the front yard of the historic property due to its
proximity to the resource.
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 lightwells.
Following the previous HPC meeting, the applicant has moved the proposed lightwell that was
abutting the historic porch to the west elevation of the historic building. The new location will
require a setback variation but is no longer immediately adjacent to the historic porch and main
entrance to the Victorian. Staff recommends the applicant work with staff and monitor and the
Building Department to discuss the options for a flat grate around the front most lightwell rather
than a railing. A rail in this location is visually intrusive. The height of any curb needs to be 6” or
less.

Staff finds the criteria for relocation are met. Staff supports the new location of the front lightwell
and the removal of the spruce tree to the front of the property. Staff recommends the applicant
continue to work closely with other City Departments related to excavation staying within the property
boundaries and obtaining the necessary permission at the time of before any work commences on
site.
2. New Addition – Connecting Element & Form/Materials/Fenestration & New Dormer: The
proposed addition has a flat roof, but is taller than the historic building and has an above grade
floor area is not larger than the historic resource. The transitional space between the old and the
new has been revised to a 5’ long one-story connecting element. A new dormer is proposed on
the rear of the historic roof.
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 revised design
is a 5’ long one-story connecting element that is minimal and subordinate to the historic eave.
Although it is not the recommended 10’ in length, the constraints on the lot creates a limited area
for new development. Staff finds that the proposed connecting element is appropriate because
of its minimal impact to the historic resource. It achieves separation 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 visually compatible with the historic resource. 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.

130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com
Figure 5 – Proposed West Elevation (revised)
Form: The revised form of the above grade addition is a two-story rectilinear massing located to
the rear of the property. A flat roof is proposed with a rooftop deck and green roof for storm water
mitigation purposes. The applicant is deviating from form and relating to the historic resource
through fenestration and building materials. Guideline 10.11 calls for a compatible roof form for
the new addition in relation to the historic resource. Typically, a gable roof is encouraged for an
addition to a historic Victorian. In order to balance the request for an adequate connecting
element, staff supports the proposed roof form because it does not visually compete with the
historic resource and is considerably setback from the front of the property.
Figure 6 – Proposed Roof Plan (revised)
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 applicant plans to restore the historic brick foundation. The revised
addition is clad in horizontal wood siding as the primary building material. Staff supports the use
of wood siding material for the new addition
Page 7 of 11
130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com
Fenestration: The revised fenestration choices on the new addition are based on the proportions
and dimensions of the historic fenestration, which is predominantly double-hung windows. The
connecting element is mostly glass. Staff finds that the revised design for fenestration relates to
the historic resource and meets the Design Guidelines.
New Dormer: In this restudy, the applicant introduced a new dormer element on the roof of the
historic resource. Visually, it is a seamless continuation of the south facing historic cross gable.
There is a large window opening at the northern gable end of the dormer. Design Guideline 7.6
addresses the addition of a new dormer to a historic roof. The proposed dormer is not providing
livability to an upper story, as typical with these features, and the mass and scale of the dormer
addition is not subordinate to the historic ridgeline. The original massing of the historic cross
gable would be altered with this design. The extension of the cross gable causes confusion
regarding the form of the historic building and covers a large portion of the historic roof. Staff
finds that this dormer addition does not meet the Design Guideline and does not recommend
approval.
Staff finds that the revised design of the new addition deviates from form but successfully relates to
the historic resource through fenestration and materials. Staff finds the proposed 5’ long one-story
connecting element achieves the appropriate separation between new and old. Staff does not
recommend approval of the proposed dormer addition.
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:
With this project, the applicant requests additional setback variations for the project:
• 2’ setback reduction on the west and east sideyard above and below grade, for the addition
• 5’ setback reduction on the east sideyard above and below grade, for historic house and
basement
• 2’ setback reduction on the west sideyard above and below grade, for the historic house
and basement
• Up to a 5’ west sideyard setback reduction for the lightwells
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
Page 8 of 11
130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com
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 parking spaces for single-family residence. Due to the site
configuration and the location of the historic resource, the applicant proposes one on-site parking
spot and a potential compact car parking space, both accessed from the alley. A compact car
parking space would not meet the code requirements, therefore, a parking reduction of one space
is requested.
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.
The revised design includes a rear loggia that functions as the entry to the compact car parking
space. The applicant’s design intent for the loggia is to break up the mass and scale of the addition
and respond to the context of the ally. A restudy of this feature may provide the extra space
needed to accommodate for a full parking space, and staff recommends restudy.
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 loggia to the rear of the proposed addition in order to provide for an adequately sized
parking space.
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. 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:
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;
Page 9 of 11
130 South Galena Street Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com
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.
Staff finds that all of the applicable criteria for a floor area bonus are met with the revised design. The
applicant provided a preservation plan to restore significant details related to the fenestration,
foundation, and the historic chimney. Staff recommends the applicant work closely with staff and monitor
on preservation details and supports the awarding of a floor area bonus.
