NEW BUSINESS: 925 King Street- Minor Subdivision Lot Split, Relocation, Demolition,
Historic Designation Boundary Line Amendment, Establishment of TDRs.
Mr. Moyer moved to continue 925 King Street to January 27, 2021; Mr. Kendrick seconded. All
in favor. Motion carried 3-0-2
NEW BUSINESS: 423 N. Second Street- Conceptual Major Development, Relocation. Bill
Guth and Ro from Rockett Design and Anne Mcnulty Owner.
Ms. Simon said that this is a really exciting project for HPC, that this is a really large Victorian
house, and that Aspen does not have too many of these structures left. She explained that the
house was relocated to its current location in the 50’s and for unknow reasons repositioned so the
front door faces the alley. Ms. Simon added that throughout the year's additions were added like
the wrap around porch, breakfast nook. She stated that the design team taking on this project has
worked on restoration projects successfully in Aspen, citing 124 West Hallam. Ms. Simon stated
that she appreciates how much time and research has gone into this project and the compromise
the owner has taken.

REGULAR MEETING HISTORIC RESERVATION COMMISSION DECEMBER 16 2020
Ms. McNulty stated that they are very appreciative of the opportunity to present the project. She
gave a brief description of her family's ties to Aspen. She said that the plan that will be present
will show a lot of improvements and be practical for her family's use.
Mr. Ro reviewed the location of the historic resource in the West End of Aspen and how the
resource sits on the lot. He showed an existing layout of the lot and indicated where key features
are like the front door opening into the alley, the added wrap around porch, and the garage
opening up on to Smuggler St. Mr. Ro reviewed the history of the resource and the original
location which was on Center St. and W. Francis S and then relocated and realigned to where it
sits today. Mr. Ro showed a historic timeline that indicated when any addition was added to the
historic resource and said that the obstacle that is at hand is removing the additions while a
historic resource is underneath. He showed a detailed list of the non-historic additions on the
outside and showed the careful probing work that was done on the internal structure to indicate
historic vs non-historic. Mr. Ro stated that the proposed plan would be to remove all the non-
historic additions, shift and rotate the historic resource lining the front entrance to Second St,
adding of the new addition that extends to the southwest corner with a one-story linking element
and garage opening to the alley. He said that due to the nature of the lot there will be a healthy
buffer between the new addition and the streets. He explained that from Second St. there is 63’-
1” buffer to the new addition and 30’-1” setback from the Victorian. He said that there is 84’-0”
from the Smuggler St. curb and just under 54’ from the front setback. Mr. Ro stated that the main
living area and hub will remain in the historic resource and the supporting facilities and garage
will make up the addition. Mr. Ro showed the proposed design for the exterior elevation showing
that the new addition will be 8’-5” lower than the resource. He showed renderings from all
angels to showcase how the resource and the new addition would sit together. Mr. Ro stated that
the flat roof form was chosen to keep a quiet form that compliments and is an appropriate
contrast to the gable pitch of the resource. He said that the material for the siding of the new
addition would be a long and skinny brick that is light and muted to complement the resource
siding. He added that there will be wood fenestrations to warm the building. Mr. Ro said that the
base of the historic home will have a painted metal base that is neutral.
Mr. Guth stated that one of the directives from the owners was to make this whole project
welcoming and friendly. He said that this is one of the last grand Victorian homes in Aspen so
there was extra thought and care when discussing and planning the new addition.
STAFF COMMENTS: Ms. Simon stated that there are a few items that need to be restudied.
She said that the east side deck off the connecting element should be eliminated or at the least
brought down to a grade-level patio, to create a more sensitive outdoor living area. Ms. Simon
stated that the applicant submitted a stormwater mitigation plan that is simple however, there is a
dry well that is being proposed on the southeast corner of the property and typically any
foreground stormwater structures like this are to be avoided. She suggested that a sod lid could
help this situation and said that this can be resolved at the next review. Ms. Simon stated that
there is a concern with the fenestration on the non-historic bump-out that faces Smuggler St. She
explained that the plan shows for large windows that are not characteristic of the resource. Ms.
Simon pointed out that the non-historic front door will need to be redesigned to risible what was
once there, a half-light door. Ms. Simon stated that this project does not need to meet the 10’
length requirement for a linking element because the addition is not taller than the resource. She
added that there will need to be discussions about the screening element for the activities that are
planned on the roof of the connector. Ms. Simon said that the proposed metal foundation band
was expectable. She stated that there is a recommendation for a restudy for the location of the
5
REGULAR MEETING HISTORIC RESERVATION COMMISSION DECEMBER 16 2020
new addition. Ms. Simon explained moving the addition 10’ to the west so it is not encroaching
on the resource as much. She added that it is typical to see an addition come from the back not
the side of a resource and would like to give the resource as much room as possible. Ms. Simon
stated that without the gable roof form to link the two structures the material must, especially the
siding facing Second St. Ms. Simon stated that staff is recommending continuation of this
project.
Mr. Moyer asked if they discourage activities on a roof without a screening element.
Ms. Simon said that there have been times they have discouraged it, Especially when the new
addition is taller than the historical resource. She said in this case we are asking for a screening
element to obstruct partial visibility.
Mr. Moyer asked if the non-historic bump-out facing Smuggler St. should have different siding
to indicate the historic vs non-historic.
Ms. Simon stated that is not necessary nor would she want to call that much attention to it.
Ms. Greenwood stated that keeping the bump-out is wrong and does not understand the staff
position to keep it.
Ms. Simon stated that the position is, acknowledging how much is being removed from the
building successfully already, and understanding that the internal livability of that space is very
valuable.
Ms. Greenwood stated that this is a mistake and the applicant could make up the floor area in a
different area.
Mr. Kendrick asked how old is the bump-out.
Ms. Simon stated that it was added after the relocation in the ’50s.
Ms. Thompson asked if a variance is needed for the light well on a street-facing façade.
Ms. Simon stated that it is recessed behind the front-most façade.
Mr. Guth stated that he would like to address some of Ms. Simon's statements.
PUBLIC COMMENT: None
COMMISSIONER COMMENTS: Ms. Greenwood stated that HPC should discuss the
guidelines 10.3 and 10.6.
Ms. Sanzone stated that it would be helpful to hear from the applicant in response to Ms. Simon's
presentation.
Mr. Guth stated that the form of the new addition was studied very heavily and had a hard time
finding something that did not compete with resources. He explained that the flat roof is quieter
and subtle. Mr. Guth said that they have no problem altering the east side deck to a stone patio
and flushing out the details. The sod lid on the dry well is not a problem and that is the intent. He
stated that the fenestration on the non-historic addition is a place holder to mimic the resource
and is intended to be refined for the final review. The front door was an oversite and is planned
to be a half-light door. Mr. Guth stated that replacing the glass railing on the connector roof with
a screen element is welcomed. He said that there will be a great detail in restoring the original
front deck. He said that the placement of the addition is in the best location. He explained that
the side where the connector is located has been altered so much already and the setbacks are
pretty large.
Mr. Moyer stated that the community will view this house as it sits now with a large welcoming
wrap-around porch. He warns of the uproar that happened with the Paepcke house project.
Mr. Kendrick stated that he agrees with Ms. Simon that this will be a successful project. He said
that the placement of the new addition is in the best placement possible. Mr. Kendrick stated that
6
REGULAR MEETING HISTORIC RESERVATION COMMISSION DECEMBER 16 2020
if the form will not be a gable relation then the material and fenestration are pretty far off. He
said he supports moving this forward while monitoring final details.
Ms. Sanzone stated that she agrees with Mr. Kendrick’s comments. She said that the placement
of the new addition works great with the resource and if moved would take away from the
simplicity of the design and not let the Victorian standout. Ms. Sanzone stated that she supports
the raised porch on the connector element. She explained that the site is very flat and to achieve
positive drainage a flat patio would make that very difficult. She commends the design team for
keeping all the historic Cottonwood and Aspen trees.
Ms. Thompson said that she agrees with the staff and previously made comments. She said that
form and fenestration is the biggest topic for this project. Ms. Thompson stated that the material
and fenestration should be restudied. She said that the relocation is very successful and the site
plan as well. Ms. Thompson said that she is not opposed to keeping the non-historic bump-out on
the Victorian in light of how much work is going into the restoration. Ms. Thompson stated that
she agrees with Ms. Sanzone about the east side deck however, it should not meet the resource.
Ms. Greenwood stated that she agrees with Ms. Thompson. She said that the form and
fenestration have not been met but the location of the new addition and the linking element is
perfect. Ms. Greenwood said the relationship between the new architecture and the old
architecture is pretty strong when viewed on Second St. except for 10.3 in the design guideline.
She explained that in 10.3 a corner lot new addition cannot deviate in form from the historic
resource. Ms. Greenwood further explained since the project does not meet the guideline it must
be continued and restudied. Ms. Greenwood asked the board how they feel about continuation in
regards to design guidelines.
Mr. Kendrick stated that there is no need to continue, the applicant has addressed enough of the
issues that it can move forward.
Ms. Greenwood stated that they have not addressed 10.3 and 10.6. She said that the new addition
as a stand-alone is a great building however, with the resource there is no story to tell.
Mr. Kendrick asked if this issue could not be addressed with fenestration and materials.
Ms. Greenwood said that she droughts that they will do tiny little windows on a modern flat roof
building. She said that you almost have to do a roof form that relates to the resource citing 10.3.
Mr. Guth stated that these are guidelines and not strict rules. He reiterated that there has been
extensive study done on the form and believed that all competed with the resource.
Ms. Greenwood stated that Ms. Thompson and herself are architects, and they are sharing their
opinion on what will make this a better project.
Mr. Moyer stated that he would rather see the new addition be its own element and not fully
relate to the resource.
Ms. Greenwood disagreed with Mr. Moyer and stated that there does need to be a visual link
between the two.
Mr. Moyer said that is true and the project at hand, the new addition does not take away fr the
resource.
Ms. Thompson stated that how she interoperates the guidelines is not to the letter rather a
principle application. She said that there needs to be sensitivity to how the two relate.
Mr. Kendrick stated that he agrees with Ms. Thompson. He said it does not have to have a gable
and if you do that you will lose another part of 10.3 in terms of being subordinate and differential
and modest because you will be adding more mass to the additions.
Ms. Thompson said she agrees with Ms. Greenwood and the staff to continue.

REGULAR MEETING HISTORIC RESERVATION COMMISSION DECEMBER 16 2020
Ms. Sanzone stated that she is torn between moving forward and continuation. She said she
would support moving this forward. She explained that the applicant has heard HPC’s concerns
and trusts that they will be addressed.
Mr. Moyer stated that he is in support of moving this forward and has addressed almost all of the
staff's concerns.
Mr. Kendrick stated he agrees that this could move forward and with the feedback given they
will be able to address the concerns.
Ms. Greenwood stated that this is sending a strong message to architects that guidelines don’t
matter.
Mr. Kendrick stated that he does not agree with Ms. Greenwood that they are that far off the
guidelines.
Ms. Thompson stated that this does not set a precedent for the board.
Ms. Simon stated that the guideline will have to be addressed at final that the decision that is
being made now is for the form and that cannot be changed.
Ms. Greenwood said that her stance has changed since they have to meet the guideline
regardless.
Mr. Kendrick stated that he is reconsidering for a continuance so the applicant can address the
concern for the form if needed.
Ms. Greenwood stated that the staff’s recommendations are good.
Ms. Simon stated that she forgot to mention that there is a setback variance being asked for. She
explained that the garage, deck on the garage, and basement are intruding on the 10’ setback by
5’. Ms. Simon said that the staff supports the request.
Ms. Greenwood said that she always supports the alignment of the garage and basement. She
said that is just good building practices.
The board agreed with variance.
Ms. Sanzone moved to approve Resolution #027-2020 with added condition #3; Mr. Moyer
seconded.
Ms. Thompson asked if this was a resolution of approval or continuance.
Ms. Greenwood stated it was for approval as presented.
Roll Call: Mr. Kendrick, Yes; Mr. Moyer, Yes; Ms. Thompson, No; Ms. Sanzone, Yes, Ms.
Greenwood; Yes. All in favor, Motion carried 4-1.
Mr. Guth thanked Ms. Greenwood for her service on HPC and stated that it was a pleasure to
work with her.
Ms. Thompson asked if there could have a discussion in the new year about the approval process.
Mr. Moyer stated that he would like to have this discussion as well. He said he will miss Ms.
Greenwood.
Ms. Johnson thanked Ms. Greenwood for her service.
Mr. True thanked Ms. Greenwood for her service.

BACKGROUND:
1020 E. Cooper Avenue is a designated 4,379 square foot lot in the Residential Multi-Family
(RMF) zone district. The site contains a Victorian era home and two sheds of an unknown
construction date. This area of town was not included in the historic Sanborn maps that are
typically referenced by HPC in its decision-making, and no historic photos of this house have
been located. The only record of the building, other than what can be discovered on-site, is the
1896 Willit’s Map, which shows the footprint (Figure 2). Investigation of the framing of the house
has demonstrated that the form of the 19th century home remains intact.
The exterior of the house has been altered over time through replacement of materials and
windows (Figure 3).
REQUEST OF HISTORIC PRESERVATION COMMISSION (HPC)
The Applicant is seeking the following land use approvals. Please note that there are no
variations requested for the project:
• Conceptual Major Development (Section 26.415.070.D) to modify the site and the historic
resource, and to construct a new detached building along the alley.
• Relocation (Section 26.415.090) to relocate the historic resource to minimum front-yard
setback required by zoning (five feet) and to excavate a new basement and foundation
below the structure.
• Demolition (Section 26.415.080.A) to remove two non-historic outbuildings from the
property.
• Growth Management (Section 26.470.050.B) & (Section 26.470.070.4) to develop five
affordable housing units on the property.
• Certificate of Affordable Housing Credits (Section 26.540) to generate Certificates of
Affordable Housing Credit.
Figure 3: 1020 E. Cooper Avenue, 2019 Figure 2: Willit’s Map, 1896
10
Page 3 of 13
• Transportation & Parking Management (26.5151.010) to meet the minimum parking and
Transportation Mitigation standards.
The Historic Preservation Commission (HPC) is the review authority on this application, however
Conceptual approval is subject to Call-up Notice to City Council. Final approval will be needed
before the project proceeds to building permit.
Per Land Use Code section 26.304.035 the applicant was required to provide enhanced public
notice and neighborhood outreach, as is typical for projects of community interest. A website
and information meetings provided detailed information to those interested prior to this HPC
review.
STAFF COMMENTS: Exhibits A.1 through A.6 to this memo provide the review criteria for each
requested approval, and recommended findings. The following is a summary of those review
criteria and recommendations.
Conceptual Major Development
Section 26.415.070.D.3.c.2 of the Municipal Code states that Conceptual review approval shall
be binding upon HPC in regards to the location and form of the envelope of the structure(s)
and/or addition(s) including its height, scale, massing and proportions, therefore design
guidelines related to those topics are the focus of this review step. The details of the
preservation plan, landscape plan and fencing, lighting, fenestration, and selection of new
materials will be addressed at Final.
Staff finds the proposal to preserve the historic resource as free-standing, with a detached and
adequately distanced new structure at the rear of the lot to be a successful preservation
outcome. There are only a few examples of miner’s cottages in Aspen that have been preserved
with no significant addition, as this one will be.
Regarding the site plan, no variations are needed, and the applicant plans a traditional
landscaped setting adjacent to the historic resource with grass and planting beds. A tree that
straddles the property line with the neighbor to the east is being preserved in coordination with
the requirements of the Parks Department. Parking and infrastructure are all designed to meet
City requirements and located at the rear of the site as required. A preliminary stormwater
mitigation plan is provided, indicating a drywell will be located within the parking area. This
strategy is appropriate and has no effect on the historic resource.
The historic resource is to be placed on a new basement. The basement includes the required
egress lightwells, which have been located discretely on the sides of the building. The visual
impacts of the lightwells, including curb heights and protective grates, needs to be minimized for
Final review.
The applicant plans to retain the existing form of the historic resource including a modestly sized
1960s era non-historic addition, as is allowable within the preservation guidelines. As the project
evolves towards final design, details of an appropriate rehabilitation that reflects common
characteristics of Aspen’s mining era homes, such as a front porch, will be evaluated. Staff does
recommend one amendment to the project regarding the treatment of the historic home, which
is removal of the two storage closets proposed directly to the west side of the Victorian as
changes in the form reduce the architectural integrity of the building.
11
Page 4 of 13
Regarding the new building proposed along the alley, a detached structure is preferred by the
HPC guidelines and is allowed greater design flexibility than an addition to a historic resource
because demolition to historic fabric does not occur and the scale and integrity of the resource
are more authentically preserved.
The applicable guidelines for new construction as expressed in Chapter 11 are primarily written
to anticipate a new structure being proposed directly next to a historic resource, for instance in
a historic landmark lot split where the new and old structures would be side by side. The impact
of the height of the rear building on the historic resource will be reduced because of its placement
some distance behind it.
Staff supports the proposed new structure as the appropriate gestures towards the historic
resource have been made. The context of the property, and the fact that it is a mid-block lot,
allow for the addition to appear as a backdrop. It is unnecessary for the new building to have a
front porch, as suggested by guideline 11.2, because there would be no visibility from the street.
The architect has creating a relationship to the historic structure by using roof forms and material
references as required by guideline 11.6. The plate height on the upper floor is low at building
corners, with dormers used to balance massing and livability considerations.
Relocation
The existing home, except for a non-historic porch at the rear, is to be moved approximately 12’
forward and 2’ eastward. It will be placed on a new basement and will be elevated slightly above
the current relationship to grade to allow for positive drainage to be created. One step will be
constructed leading to the porch deck. Staff finds that the relocation criteria are met as the re-
positioning of the building on the site does not diminish its integrity or disrupt its relationship with
nearby historic resources and it allows new construction on the site to be adequately distanced
from the miner’s cottage while complying with all setback requirements.
Demolition
Two sheds at the rear of the property and partially sitting in the alley are proposed to be
demolished. These structures were not built concurrent with the primary home based on the
1896 Willit’s map, and they are not seen in 1920s era photos of the rear of the site available
from the Aspen Historical Society. The earliest documentation of them in place that staff has
located is a 1974 aerial photo. The property was designated as a representation of the 19th
century development of Aspen, therefore staff finds the sheds to be non-contributing to the
history of the property and appropriate for removal.
Growth Management and Certificates of Affordable Housing Credit:
A total of five deed-restricted affordable housing units are proposed for the site- two in the
historic resource and three in the rear building. This application was referred to APCHA for
review and recommendation. Community Development & APCHA staff are highly supportive of
this project and acknowledge the community benefit that five affordable housing units will bring.
The applicant seeks to establish 12.75 Certificates of Affordable Housing credits, which is
commensurate to the mitigation standards prescribed by APCHA. Pursuant to Land Use Code
Section 26.540.070, Review Criteria for establishing an affordable housing credit, to determine
the number of certificates of affordable housing credits awarded to a project, the review

Three of the units exceed the minimum dimensional standards prescribed by APCHA, and two
of the units are roughly 16 percent below the minimum size requirements1. Four parking spaces
are provided on site (including an ADA-compliant space), which is well above the minimum
required2. The site will also contain plenty of outdoor area, including access to private patios
and porches. Each unit will contain a washer and dryer as well as extra storage space. Lastly,
as required in the Land Use Code, more than half the net livable area of each unit will be above
natural grade. Despite the slight reduction in size, staff considers these as high-quality units
that incorporate several valuable amenities.

Affordable housing and in-fill development are important City policy objectives, as stated in the
2000 Aspen Area Community Plan (AACP) and reiterated in the 2012 AACP:
Our housing policy should bolster our economic and social diversity, reinforce variety, and
enhance our sense of community by integrating affordable housing into the fabric of our town. A
healthy social balance includes all income ranges and types of people. Each project should
endeavor to further that mix and to avoid segregation of economic and social classes…”
Within the area surrounding 1020 E.
Cooper, there is a limited number of deed-
restricted affordable units. As depicted in
Figure 7, only four deed-restricted units
are located within the immediate vicinity of
the property.
As proposed, this project will serve an
important role in achieving community
policy goals with respect to the location,
quantity, and quality of affordable housing
in Aspen.

1. On-street parking in this area requires a permit. The Parking Department caps the
number of permits per residence, minimizing on-street parking congestion in the area.
Transportation and Parking Management:
Pursuant to Land Use Code Section 26.515.060.C, Transportation & Parking Management, one
parking unit is required per residential unit within a multi-family development, in this case five.
The City’s parking regulations are the result of professional parking studies, Council
consideration, and public input, and they are applied objectively to all development types.
The Residential Multi-Family
(RMF) zone district allows 100
percent of parking mitigation
to be met via cash-in-lieu or
via a combination of cash-in-
lieu and on-site parking. This
is due to the location of the
zone district in the community,
proximal to mass transit,
walkable to all community services and amenities, and zoned to provide moderately dense
housing development. The site is located less than one minute from a bus stop and 0.2 miles
from the commercial center of town.
In addition to the transit and multi-modal services accessible to the site, four on-site parking
spaces are proposed, including one ADA-accessible space. These spaces are on the alley and
located beneath a covered area of the rear addition. Remaining parking mitigation will be met
via cash-in-lieu.
Staff supports the parking mitigation as proposed, and it complies with the regulations in the
Land Use Code. Providing on-site parking is generally preferred to cash-in-lieu as it reduces
adverse parking impacts to the surrounding neighborhood. In this case, 80 percent of the
required parking mitigation will be met on-site, which contributes to the livability and quality of
this project. Furthermore, given the residential use of the surrounding neighborhood, on-street
parking exists throughout the area.1
In addition to the on-site parking,
the applicant has completed the
Transportation Impact Analysis
(TIA) for this project and plans to
provide a range of Mobility
Measures that satisfy the
requirements of the Engineering
and Parking Departments. At this
point, the applicant has indicated
that car-sharing and bike-sharing
memberships will be made
available to tenants for a minimum
of one year. Bicycle parking will
also be provided on-site, and other
infrastructure improvements will be
made to encourage alternative

transportation choices. The TIA is subject to change and will be assessed at building permit.
Staff included a condition in the Resolution prohibiting Mobility Measures from occupying any of
the off-street parking spaces on the property.
RESIDENTIAL DESIGN STANDARDS
The Residential Design Standards found at Section 26.410 of the Municipal Code apply only to
the new structure proposed for this site. RDS review is an administrative process which does
not require public notice or evaluation by HPC. The standards applicable to multi-family
development are limited. The applicant has provided a compliance form which has been verified
through a staff level approval.
DRC REFERRAL COMMENTS:
The application was referred out to other City departments who have requirements that will
significantly affect the permit review. The applicant responded to initial feedback from these
departments by revising their application to what is being presented to HPC. Following is a
summary of topics that may require further study before HPC Final review or as part of the
building permit process. All are expected to be resolvable.
Engineering:
1. Fire flow calculations will be required if a 4-inch service line is needed. Calculations that
show a 2-inch service line fails will also need to be provided.
2. The conceptual drainage report calls out that the alley will be re-designed to accommodate
flows to the curb and gutter, this design will need to be included with capacity calculations.
3. The transformer to the east has an existing easement that, according to the conceptual
drainage report, is adequately sized for a future relocation. Show the dimensions of the
easement (on 1020 E. Cooper and the neighboring property) on the utility plan to confirm
the easement meets COA Electric standards for transformer easements. If the dimensions
do not comply with COA standards, the easement will need to be adjusted during building
permit review.
Building:
1. Fire sprinklers are required with five units on the site regardless of the fire area measurement.
2. There cannot be an emergency escape and egress window well in a walkway.
3. Amendments to the IBC require 3% of the parking to be electric vehicle charging stations
capable of supporting future EVCS. A 208/240 volt branch circuit or listed raceway to
accommodate future installation shall be installed. Service panel or sub panel circuit shall
provide capacity for a dedicated 40 amp circuit.
4. Demonstrate compliance with IBC 1107.7.1.1 at least one story containing dwelling units
shall be provided with an accessible entrance on an accessible route and shall comply as a
Type B unit.
5. Ensure the steel beam between the van accessible spot and the aisle won’t block access
from an accessible van’s passenger rear side door as that would normally be how the aisle
is utilized from the van.
6. Trash enclosure is required to be on an accessible route. Demonstrate required door
maneuvering clearances inside the enclosure.
7. Demonstrate compliant common path of egress travel distances from each unit, measured
from the most remote point within each unit to the exit discharge.
8. All new roofs or re-roofed areas are required to be a class A rated roof assembly.
18
Page 11 of 13
9. Eaves and exterior walls within 5’ of the property line require 1 hour fire rated construction.
10. Snow guards are also required on the historic home, not just the new construction.
11. All guards are required to be 42-inches tall in an IBC building unless you are inside the
dwelling unit.
12. Storage closed under the common stair to the upper units requires a compliant dwelling
separation for the closet ceiling.
13. Provide compliant approach to the washer dryer.
14. Closet doors need to provide 32” clear opening.
Parks:
1. Maintain 10-foot dripline protection for shared tree – Any activity or excavation in this area
will require City Forester approval.
2. Planting trees back on this property should be explored and supported.
Environmental Health
1. This space is subject to the requirements of a multi-family complex and is required to provide
120 square feet of space to the storage of trash and recycling. The current application
exceeds these standards by providing 124 SF.
2. Applicant indicates alley access will be facilitated by the ADA parking access to provide an
unobstructed path to the trash area.
3. Applicant has indicated this space will be equipped with bear-proof technology to prevent
wildlife access.
APCHA
1. Prior to Certificate of Occupancy, a deed restriction must be recorded and must comply with
the APCHA Regulations in effect at the time that said deed restriction is approved and
recorded.
2. Each bedroom must contain a closet.
3. Each unit shall contain a washer and dryer, along with all other appliances.
4. The units that do not meet the minimum size requirements are acceptable as they are within
the 20% reduction limitation and fit the criteria for said reduction acceptance.
5. Upon certificate of occupancy, affordable housing credits can be provided for up to a total of
12.75 FTE’s based on the generation rate established in the Regulations and calculated as
follows:
3 2-bedrooms X 2.25/bedroom = 6.75
2 3-bedrooms X 3.00/bedroom = 6.00
TOTAL 12.75 FTE’s
RESPONSE TO PUBLIC COMMENT:
Public comment received prior to packet deadline is attached as Exhibit C. Staff will be prepared
to respond to questions in more detail at the HPC hearing. To briefly address some topics
requiring clarification, a letter submitted on behalf of the HOAs for the condominiums on the east
and west sides of the subject lot suggests that the application is proposing unlawful selling of
the individual units prior to subdivision. At the conclusion of construction, prior to the issuance
of a Certificate of Occupancy, the standard practice is for the City to process a condominium
application separating ownership, and to work with the applicant and APCHA to record deed
19
Page 12 of 13
restrictions that will ensure the proper occupancy of the units in perpetuity. The sale of the
legally condominiumized units does not violate the requirements of affordable housing deed
restrictions for rental properties, so long as the occupant of the rental units meets applicable
APCHA requirements.
The same letter expresses concern that the project is not complying with ADA requirements and
that the ADA parking space on the property is exclusively for the use of a person with a disability.
The Building Department has, through a detailed preliminary evaluation, worked with the
architect to ensure ADA compliance. The ADA parking space will be associated with the
accessible unit, which may or may not be occupied by individuals requiring such accessibility.
The presence of the unit and appropriate design features to permit ADA occupancy is sufficient
to meet the law. The Building Department and Fire Department have also preliminarily
confirmed that the project meets required Fire Codes as proposed. The project must meet
required distances and precautions related to its own property lines, not related to the distance
of adjacent structures. The units will have fire sprinklers.
A question has been raised as to the options for development on this property given that it is
smaller than the standard minimum lot size of 6,000 square feet. Certain dimensional
requirements, as described in Code section 26.710.090(d), apply to the zone district (RMF),
including a minimum lot width of 60 ft., . Here, the subject parcel is less than 60 ft. wide, and
therefore does not meet the applicable zone district’s minimum dimensions. Because there is
a historic structure on the lot, the lot itself is considered a historic lot of record, as provided for
in section 26.312.050(c):
“A lot of record containing a property listed on the Aspen Inventory of Historic Landmark
Sites and Structures need not meet the minimum lot area requirements of its zone district
to allow the uses that are permitted and conditional uses in the zone district subject to
the standards and procedures established in Chapter 26-415.”
This code section assumes that, because a lot of record does not meet the minimum lot area for
the underlying zone, it will by definition fail to meet one or more other dimensional requirements
(i.e. width or length). It explicitly permits development on such lots in recognition of their historic
condition. Whether it is due to shortages in lot length or width, failure to meet the dimensional
lot area requirements of the underlying zone district is not grounds to prohibit use of the site for
multi-family development as historic lot exemptions apply. The proposed use of a multi-family
residence is allowed in the zone district (RMF). See section 26.710.90(b).
One other important note is that, while it is true that section 26.312.030 states that
nonconforming structures may not be extended or enlarged, the section expressly provides that
Historic Structures are again cause for exception with regard to dimensional criteria. Historical
structures may be extended into the front yard, side yard and rear yard setbacks, and may also
be extended into the minimum distance between buildings on a lot and may be enlarged.
RECOMMENDATION:
Staff supports the project, and the achievement of community goals through the preservation of
a historic resource and development of affordable housing units within an established multi-
family neighborhood in the infill area are supported by adopted City regulations and policies.
Staff recommends the following motion:

property or a property located within a Historic District until plans or sufficient information have
been submitted to the Community Development Director and approved in accordance with the
procedures established for their review. An application for a building permit cannot be submitted
without a development order.
1. Conceptual Development Plan Review
b) The procedures for the review of conceptual development plans for major development
projects are as follows:
1) The Community Development Director shall review the application materials
submitted for conceptual or final development plan approval. If they are
determined to be complete, the applicant will be notified in writing of this and a
public hearing before the HPC shall be scheduled. Notice of the hearing shall be
provided pursuant to Section 26.304.060.E.3 Paragraphs a, b and c.
2) Staff shall review the submittal material and prepare a report that analyzes the
project's conformance with the design guidelines and other applicable Land Use
Code sections. This report will be transmitted to the HPC with relevant information
on the proposed project and a recommendation to continue, approve, disapprove
or approve with conditions and the reasons for the recommendation. The HPC will
review the application, the staff analysis report and the evidence presented at the
hearing to determine the project's conformance with the City Historic Preservation
Design Guidelines.
3) The HPC may approve, disapprove, approve with conditions or continue the
application to obtain additional information necessary to make a decision to
approve or deny.
4) A resolution of the HPC action shall be forwarded to the City Council in
accordance with Section 26.415.120 - Appeals, notice to City Council, and call-up.
No applications for Final Development Plan shall be accepted by the City and no
associated permits shall be issued until the City Council takes action as described
in said section.
Relevant Historic Preservation Design Guidelines for Conceptual Review of this
application:
1.1 All projects shall respect the historic development pattern or context of the block,
neighborhood or district.
• Building footprint and location should reinforce the traditional patterns of the
neighborhood.
• Allow for some porosity on a site. In a residential project, setback to setback development
is typically uncharacteristic of the historic context. Do not design a project which leaves
no useful open space visible from the street.
1.2 Preserve the system and character of historic streets, alleys, and ditches.
When HPC input is requested, the following bullet points may be applicable.
28
Exhibit A.1
Historic Preservation Design Guidelines
Staff Findings
Page 4 of 14
• Retain and preserve the variety and character found in historic alleys, including retaining
historic ancillary buildings or constructing new ones.
• Retain and preserve the simple character of historic ditches. Do not plant flowers or add
landscape.
• Abandoning or re-routing a street in a historic area is generally discouraged.
• Consider the value of unpaved alleys in residential areas.
• Opening a platted right of way which was abandoned or never graded may be
encouraged on a case by case basis.
1.5 Maintain the historic hierarchy of spaces.
• Reflect the established progression of public to private spaces from the public sidewalk
to a semi-public walkway, to a semi private entry feature, to private spaces.
1.6 Provide a simple walkway running perpendicular from the street to the front entry
on residential projects.
• Meandering walkways are not allowed, except where it is needed to avoid a tree or is
typical of the period of significance.
• Use paving materials that are similar to those used historically for the building style and
install them in the manner that they would have been used historically. For example on
an Aspen Victorian landmark set flagstone pavers in sand, rather than in concrete. Light
grey concrete, brick or red sandstone are appropriate private walkway materials for most
landmarks.
• The width of a new entry sidewalk should generally be three feet or less for residential
properties. A wider sidewalk may be appropriate for an AspenModern property.
1.7 Provide positive open space within a project site.
• Ensure that open space on site is meaningful and consolidated into a few large spaces
rather than many small unusable areas.
• Open space should be designed to support and complement the historic building.
1.8 Consider stormwater quality needs early in the design process.
• When included in the initial planning for a project, stormwater quality facilities can be
better integrated into the proposal. All landscape plans presented for HPC review must
include at least a preliminary representation of the stormwater design. A more detailed
design must be reviewed and approved by Planning and Engineering prior to building
permit submittal.
• Site designs and stormwater management should provide positive drainage away from
the historic landmark, preserve the use of natural drainage and treatment systems of the
site, reduce the generation of additional stormwater runoff, and increase infiltration into
the ground. Stormwater facilities and conveyances located in front of a landmark should
have minimal visual impact when viewed from the public right of way.
• Refer to City Engineering for additional guidance and requirements.
1.11 Preserve and maintain historically significant landscaping on site, particularly
landmark trees and shrubs.
• Retaining historic planting beds and landscape features is encouraged.
• Protect historically significant vegetation during construction to avoid damage. Removal
of damaged, aged, or diseased trees must be approved by the Parks Department.
• If a significant tree must be removed, replace it with the same or similar species in
coordination with the Parks Department.
29
Exhibit A.1
Historic Preservation Design Guidelines
Staff Findings
Page 5 of 14
• The removal of non-historic planting schemes is encouraged.
• Consider restoring the original landscape if information is available, including original
plant materials.
1.12 Provide an appropriate context for historic structures. See diagram.
• Simplicity and restraint are required. Do not overplant a site, or install a landscape which
is overtextured or overly complex in relationship to the historic resource, particularly in
Zone A. In Zone A, new planting shall be species that were used historically or species
of similar attributes.
• In areas immediately adjacent to the landmark, Zone A and Zone B, plants up 42” in
height, sod, and low shrubs are often appropriate.
• Contemporary planting, walls and other features are not appropriate in Zone A. A more
contemporary landscape may surround new development or be located in the rear of the
property, in Zone C.
• Do not cover areas which were historically unpaved with hard surfaces, except for a
limited patio where appropriate.
• Where residential structures are being adapted to commercial use, proposals to alter the
landscape will be considered on a case-by-case basis. The residential nature of the
building must be honored.
• In the case of a historic landmark lot split, careful consideration should be given so as
not to over plant either property, or remove all evidence of the landscape characteristics
from before the property was divided.
• Contemporary landscapes that highlight an AspenModern architectural style are
encouraged.

1.23 Re-grading the site in a manner that changes historic grade is generally not
allowed and will be reviewed on a case by case basis.
1.26 Preserve the historic circulation system.
• Minimize the impact of new vehicular circulation.
• Minimize the visual impact of new parking.
• Maintain the separation of pedestrian and vehicle which occurred historically.
5.4 If reconstruction is necessary, match the original in form, character and detail.
• Match original materials.
• When reconstructing an original porch or balcony without historic photographs, use
dimensions and characteristics found on comparable buildings. Keep style and form
simple with minimal, if any, decorative elements.
5.5 If new steps are to be added, construct them out of the same primary materials
used on the original, and design them to be in scale with the porch or balcony
• Steps should be located in the original location.
• Step width should relate to the scale of entry doors, spacing between posts, depth of deck,
etc.
• Brick, red sandstone, grey concrete, or wood are appropriate materials for steps.
7.1 Preserve the original form of a roof.
• Do not alter the angle of a historic roof. Preserve the orientation and slope of the roof as
seen from the street.
• Retain and repair original and decorative roof detailing.
• Where the original roof form has been altered, consider restoration.
7.2 Preserve the original eave depth.
• Overhangs contribute to the scale and detailing of a historic resource.
• AspenModern properties typically have very deep or extremely minimal overhangs that are
key character defining features of the architectural style.
8.1 If an existing secondary structure is historically significant, then it must be
preserved.
• When treating a historic secondary building, respect its character-defining features.
These include its materials, roof form, windows, doors, and architectural details.
• If a secondary structure is not historically significant, then its preservation is optional.
The determination of significance is based on documentation of the construction date of
the outbuilding and/or physical inspection. A secondary structure that is related to the
period of significance of the primary structure will likely require preservation.
9.2 Proposals to relocate a building will be considered on a case-by-case basis.
• In general, on-site relocation has less of an impact on individual landmark structures
than those in a historic district.
• In a district, where numerous adjacent historic structures may exist, the way that
buildings were placed on the site historically, and the open yards visible from the street
are characteristics that should be respected in new development.
• Provide a figure ground study of the surrounding parcels to demonstrate the effects of a
building relocation.
• In some cases, the historic significance of the structure, the context of the site, the
construction technique, and the architectural style may make on-site relocation too
32
Exhibit A.1
Historic Preservation Design Guidelines
Staff Findings
Page 8 of 14
impactful to be appropriate. It must be demonstrated that on-site relocation is the best
preservation alternative in order for approval to be granted.
• If relocation would result in the need to reconstruct a substantial area of the original
exterior surface of the building above grade, it is not an appropriate preservation option.
9.3 Site a relocated structure in a position similar to its historic orientation.
• It must face the same direction and have a relatively similar setback. In general, a forward
movement, rather than a lateral movement is preferred. HPC will consider setback
variations where appropriate.
• A primary structure may not be moved to the rear of the parcel to accommodate a new
building in front of it.
• Be aware of potential restrictions against locating buildings too close to mature trees.
Consult with the City Forester early in the design process. Do not relocate a building so
that it becomes obscured by trees.
9.4 Position a relocated structure at its historic elevation above grade.
• Raising the finished floor of the building slightly above its original elevation is acceptable if
needed to address drainage issues. A substantial change in position relative to grade is
inappropriate.
• Avoid making design decisions that require code related alterations which could have been
avoided. In particular, consider how the relationship to grade could result in non-historic
guardrails, etc.
9.6 Minimize the visual impact of lightwells.
• The size of any lightwell that faces a street should be minimized.
• Lightwells must be placed so that they are not immediately adjacent to character defining
features, such as front porches.
• Lightwells must be protected with a flat grate, rather than a railing or may not be visible
from a street.
• Lightwells that face a street must abut the building foundation and generally may not
“float” in the landscape except where they are screened, or on an AspenModern site.
9.7 All relocations of designated structures shall be performed by contractors who
specialize in moving historic buildings, or can document adequate experience in
successfully relocating such buildings.
• The specific methodology to be used in relocating the structure must be approved by
the HPC.
• During the relocation process, panels must be mounted on the exterior of the building to
protect existing openings and historic glass. Special care shall be taken to keep from
damaging door and window frames and sashes in the process of covering the openings.
Significant architectural details may need to be removed and securely stored until
restoration.
• The structure is expected to be stored on its original site during the construction process.
Proposals for temporary storage on a different parcel will be considered on a case by
case basis and may require special conditions of approval.
• A historic resource may not be relocated outside of the City of Aspen.
10.2 A more recent addition that is not historically significant may be removed.

• For Aspen Victorian properties, HPC generally relies on the 1904 Sanborn Fire Insurance
maps to determine which portions of a building are historically significant and must be
preserved.
• HPC may insist on the removal of non-historic construction that is considered to be
detrimental to the historic resource in any case when preservation benefits or variations
are being approved.
10.3 Design a new addition such that one’s ability to interpret the historic character of
the primary building is maintained.
• A new addition must be compatible with the historic character of the primary building.
• An addition must be subordinate, deferential, modest, and secondary in comparison to
the architectural character of the primary building.
• An addition that imitates the primary building’s historic style is not allowed. For example,
a new faux Victorian detailed addition is inappropriate on an Aspen Victorian home.
• An addition that covers historically significant features is inappropriate.
• Proposals on corner lots require particular attention to creating compatibility.
10.4 The historic resource is to be the focus of the property, the entry point, and the
predominant structure as viewed from the street.
• The historic resource must be visually dominant on the site and must be distinguishable
against the addition.
• The total above grade floor area of an addition may be no more than 100% of the above
grade floor area of the original historic resource. All other above grade development must
be completely detached. HPC may consider exceptions to this policy if two or more of
the following are met:
o The proposed addition is all one story
o The footprint of the new addition is closely related to the footprint of the historic
resource and the proposed design is particularly sensitive to the scale and
proportions of the historic resource
o The project involves the demolition and replacement of an older addition that is
considered to have been particularly detrimental to the historic resource
o The interior of the resource is fully utilized, containing the same number of usable
floors as existed historically
o The project is on a large lot, allowing the addition to have a significant setback
from the street
o There are no variance requests in the application other than those related to
historic conditions that aren’t being changed
o The project is proposed as part of a voluntary AspenModern designation, or
o The property is affected by non-preservation related site specific constraints such
as trees that must be preserved, Environmentally Sensitive Areas review, etc.
10.6 Design a new addition to be recognized as a product of its own time.
• An addition shall be distinguishable from the historic building and still be visually
compatible with historic features.
• A change in setbacks of the addition from the historic building, a subtle change in
material, or a modern interpretation of a historic style are all techniques that may be
considered to help define a change from historic construction to new construction.
• Do not reference historic styles that have no basis in Aspen.
34
Exhibit A.1

• Consider these three aspects of an addition; form, materials, and fenestration. An
addition must relate strongly to the historic resource in at least two of these elements.
Departing from the historic resource in one of these categories allows for creativity and
a contemporary design response.
• Note that on a corner lot, departing from the form of the historic resource may not be
allowed.
• There is a spectrum of appropriate solutions to distinguishing new from old portions of a
development. Some resources of particularly high significance or integrity may not be
the right instance for a contrasting addition.
10.8 Design an addition to be compatible in size and scale with the main building.
• An addition that is lower than, or similar to the height of the primary building, is preferred.
10.10 Place an addition at the rear of a primary building or set it back substantially from
the front to minimize the visual impact on the historic structure and to allow the original
proportions and character to remain prominent.
• Locating an addition at the front of a primary building is inappropriate.
• Additions to the side of a primary building are handled on a case-by-case basis and are
approved based on site specific constraints that restrict rear additions.
• Additional floor area may also be located under the building in a basement which will not
alter the exterior mass of a building.
10.11 Roof forms shall be compatible with the historic building.
• A simple roof form that does not compete with the historic building is appropriate.
• On Aspen Victorian properties, a flat roof may only be used on an addition to a gable
roofed structure if the addition is entirely one story in height, or if the flat roofed areas
are limited, but the addition is primarily a pitched roof.
10.12 Design an addition to a historic structure that does not destroy or obscure
historically important architectural features.
• Loss or alteration of architectural details, cornices, and eavelines must be avoided.
11.1 Orient the new building to the street.
• Aspen Victorian buildings should be arranged parallel to the lot lines, maintaining the
traditional grid pattern.
• AspenModern alignments shall be handled case-by-case.
• Generally, do not set the new structure forward of the historic resource. Alignment of
their front setbacks is preferred. An exception may be made on a corner lot or where a
recessed siting for the new structure is a better preservation outcome.
11.2 In a residential context, clearly define the primary entrance to a new building by
using a front porch.
• The front porch shall be functional, and used as the means of access to the front door.
• A new porch must be similar in size and shape to those seen traditionally.
11.3 Construct a new building to appear similar in scale and proportion with the historic
buildings on a parcel.
• Subdivide larger masses into smaller “modules” that are similar in size to the historic
buildings on the original site.
• Reflect the heights and proportions that characterize the historic resource.
11.4 Design a front elevation to be similar in scale to the historic building.
• The primary plane of the front shall not appear taller than the historic structure.
35
Exhibit A.1

11.6 Design a new structure to be recognized as a product of its time.
• Consider these three aspects of a new building; form, materials, and fenestration. A
project must relate strongly to the historic resource in at least two of these elements.
Departing from the historic resource in one of these categories allows for creativity and
a contemporary design response.
• When choosing to relate to building form, use forms that are similar to the historic
resource.
• When choosing to relate to materials, use materials that appear similar in scale and finish
to those used historically on the site and use building materials that contribute to a
traditional sense of human scale
• When choosing to relate to fenestration, use windows and doors that are similar in size
and shape to those of the historic resource.
11.7 The imitation of older historic styles is discouraged.
• This blurs the distinction between old and new buildings.
• Overall, details shall be modest in character.
12.1 Address accessibility compliance requirements while preserving character
defining features of historic buildings and districts.
• All new construction must comply completely with the International Building Code (IBC)
for accessibility. Special provisions for historic buildings exist in the law that allow some
flexibility when designing solutions which meet accessibility standards.
12.4 Minimize the visual impacts of utilitarian areas, such as mechanical equipment and
trash storage.
• Place mechanical equipment on the ground where it can be screened.
• Mechanical equipment may only be mounted on a building on an alley façade.
• Rooftop mechanical equipment or vents must be grouped together to minimize their
visual impact. Where rooftop units are visible, it may be appropriate to provide screening
with materials that are compatible with those of the building itself. Use the smallest, low
profile units available for the purpose.
• Window air conditioning units are not allowed.
• Minimize the visual impacts of utility connections and service boxes. Group them in a
discrete location. Use pedestals when possible, rather than mounting on a historic
building.
• Paint mechanical equipment in a neutral color to minimize their appearance by blending
with their backgrounds
• In general, mechanical equipment should be vented through the roof, rather than a wall,
in a manner that has the least visual impact possible.
• Avoid surface mounted conduit on historic structures.
Staff Findings: Guidelines applicable to this level of review address Site Planning and
Landscape Design, Porches, Roofs, Secondary Structures, Relocation, Additions, New
Structures on a Landmark Property, and Accessibility and Service Areas.
The proposal to site the historic structure at the front of this property with a detached addition is
in keeping with historic preservation goals to minimize alterations made directly to a historic
resource. There are only a few examples of miner’s cottages in Aspen that have been preserved
36
Exhibit A.1

Page 12 of 14
as a free-standing structure as this one will be. This is particularly important given the small size
of this building type in comparison to the amount of square footage that the property owner has
the expectation to expand to under Aspen’s zoning allowances. In addition, the plan to program
the historic resource as mandatory occupancy housing will activate the historic resource in a
way that HPC has valued in past discussions.
No variations are needed for this project and the applicant plans a traditional landscaped setting
adjacent to the historic resource with grass and planting beds. A tree that straddles the property
line with the neighbor to the east is being preserved in coordination with the requirements of the
Parks Department. Parking and infrastructure are all designed to meet City requirements and
located at the rear of the site as required. A preliminary stormwater mitigation plan is provided,
indicating a drywell well be located within the parking area. This strategy is appropriate and has
no impact on the historic resource.
The historic resource is to be placed on a new basement. The basement includes the required
egress lightwells, which have been located discretely on the sides of the building. The visual
impacts of the lightwells, including curb heights and protective grates, needs to be minimized
and is a condition of approval.
Inspection of the home on this site has revealed that it is two separately constructed Victorian
era buildings which, early in their history, were butted against each other in an L form and
“stitched” together. This creates some challenging conditions, including differing north-south
and east-west ridge heights.
This property is outside of the area covered by the turn of the century fire insurance maps that
are often relied on for documentation of changes to buildings. No historic photos have been
located and exterior materials and windows have been altered over time. Based on the existing
information it has not been possible to tell whether or not the house had a front porch. The
applicant proposes one, which staff supports. It is to extend the roofline of the existing shed
pitch at the front of the building. Details of the porch are to be reviewed at Final. The overall
approach with regard to rehabilitation of this resource is to reflect common characteristics of
Aspen’s mining era homes. On-going physical inspection and careful review of any new
evidence uncovered during the construction process will be necessary.
During review of a previous redevelopment approval for the site, removal of the 1960s rear lean-
to addition on the north side of the resource was promoted by staff and HPC. This was primarily
because the applicant proposed to use that addition as the required connector between new and
old construction, which was found to be unsuccessful because the element did not meet the
length and width characteristics typically required for this feature. Retaining the lean-to in the
design resulted in the addition appearing to butt directly into the resource, which is not permitted.
This project does not include a rear addition. As an existing addition that has already had
impacts on the integrity of the rear façade of the Victorian era construction staff finds that removal
of the rear addition is not a priority, and HPC cannot insist on it because the project involves no
requests for bonuses or variances (see Guideline 10.2).
37
Exhibit A.1
Historic Preservation Design Guidelines
Staff Findings
Page 13 of 14
The application does include very modest expansions to the historic structure in the form of a
westward extension of the lean-to and two storage closets proposed on the west side of the
resource as shown below. Staff finds that the extension of the lean-to, including an entry porch
for the rear unit in the house, is appropriate and has no impact on historic fabric. The work also
helps to distinguish the rear construction as of a different era. The detailing and materiality that
can be used to subtly reinforce this will be discussed at Final. Staff does not support the exterior
storage closets shown at the pair of four panel doors. These are not required to meet the
affordable housing guidelines as other storage is available to the units. They are directly butted
against the historic portion of the home covering a historic wall and changing the original form
and are in conflict with guidelines 10.3, 10.10 and 10.12. Staff recommends a condition of
approval that these closets be deleted from the proposal.
Regarding the proposed new structure, it is in fact notably larger than the historic resource, but
the resource is particularly small in footprint and diminutive in height, making it difficult to express
the development rights allowed on the site in a similar form. The fact that the expansion is
detached very significantly reduces its historic preservation impact. The applicable guidelines
for new construction as expressed in Chapter 11 are primarily written to anticipate a new
structure being proposed directly next to a historic resource, for instance in a historic landmark
lot split where the new and old structures would be side by side. The impact of the height of the
rear building on the historic resource will be reduced because of its placement some distance
behind it.
Staff supports the proposed new structure as the appropriate gestures towards the historic
resource have been made. The context of the property, and the fact that it is a mid-block lot,
allow for the addition to appear as a backdrop. It is unnecessary for the new building to have a
front porch, as suggested by guideline 11.2, because there would be no visibility from the street.
The architect has creating a relationship to the historic structure by using roof forms and material
references as required by guideline 11.6. The plate height on the upper floor is low at building
corners, with dormers used to balance massing and livability considerations.
38

Staff finds the design guidelines to be met for Conceptual approval with the condition that the
closet additions on the west side of the resource are removed. Additional details of the front
porch design, and minimizing the impact of the curb height and grates on the lightwells serving
the historic home’s basement will be needed in the next step of the review process.

building, structure or object will be approved if it is determined that it meets any one of the
following standards:
1. It is considered a noncontributing element of a historic district and its relocation will not
affect the character of the historic district; or
2. It does not contribute to the overall character of the historic district or parcel on which it is
located and its relocation will not have an adverse impact on the Historic District or
property; or
3. The owner has obtained a certificate of economic hardship; or
4. The relocation activity is demonstrated to be an acceptable preservation method given the
character and integrity of the building, structure or object and its move will not adversely
affect the integrity of the Historic District in which it was originally located or diminish the
historic, architectural or aesthetic relationships of adjacent designated properties; and
Additionally, for approval to relocate all of the following criteria must be met:
40
Exhibit A.2
Relocation
Staff Findings
Page 2 of 2
1. It has been determined that the building, structure or object is capable of withstanding the
physical impacts of relocation;
2. An appropriate receiving site has been identified; and
3. An acceptable plan has been submitted providing for the safe relocation, repair and
preservation of the building, structure or object including the provision of the necessary
financial security.
Staff Findings: The applicant proposes relocation of the existing structure approximately 12’
towards the front lot line and 2’ away from the east lot line. No variations are requested.
There are two other Victorian era homes on
this blockface, though a non-historic
apartment building sits between 1020 and
those other resources, disrupting any strong
relationship between them. Based on the
1896 Willit’s map seen at right, and the
current aerial image below, buildings on this
blockface have historically lacked a
consistent front setback. (Please note that the
map at right also demonstrates that the
existing outbuildings were not present in the
Victorian era.) Staff finds that the proposed
on-site relocation of this home is an
appropriate preservation outcome because it
will provide separation between the historic
resource and the new construction, and will
improve the visibility of the historic structure.
It will not disrupt the integrity of the relationship between this historic resource and any others.
The applicant has provided a
structural engineer’s preliminary
finding that the historic resource can
be safely relocated. Standard
conditions of approval regarding
appropriate relocation techniques,
and a security to be held by the City
during construction are included in
the resolution.
Staff finds that the relocation criteria
highlighted above are met and
recommends HPC grant approval.

property owners, parties of interest and members of the general public to determine if the
standards for demolition approval have been met. Demolition shall be approved if it is
demonstrated that the application meets any one of the following criteria:
a) The property has been determined by the City to be an imminent hazard to public
safety and the owner/applicant is unable to make the needed repairs in a timely
manner,
b) The structure is not structurally sound despite evidence of the owner's efforts to
properly maintain the structure,
c) The structure cannot practically be moved to another appropriate location in Aspen
or
d) No documentation exists to support or demonstrate that the property has historic,
architectural, archaeological, engineering or cultural significance and
Additionally, for approval to demolish, all of the following criteria must be met:
a) The structure does not contribute to the significance of the parcel or Historic District
in which it is located and
b) The loss of the building, structure or object would not adversely affect the integrity
of the Historic District or its historic, architectural or aesthetic relationship to adjacent
designated properties and
c) Demolition of the structure will be inconsequential to the historic preservation needs
of the area.
Staff Findings: Two outbuildings at the rear of the property are proposed for demolition. The
construction date of these buildings is unknown. Neither appear on historic maps from the
Victorian era, demonstrating that they were not built concurrent with the primary home. The
buildings are not seen in 1920s era photos of the site available from the Aspen Historical
Society. They are in place in a 1974 aerial photo of the site.
The property was designated as a representation of the 19th century development of Aspen,
therefore staff finds that removal of these structures meets the criteria highlighted above and
recommends HPC approval.

Transportation & Parking Management
Staff Findings
26.515.060.C, Transportation & Parking Management
Staff Findings:
Pursuant to the Land Use Code, one parking unit is required for each affordable housing (AH)
unit; in this case, five parking units for five AH units. The Residential Multi-Family (RMF) zone
district allows 100 percent of parking mitigation to be met via cash-in-lieu or via a combination of
cash-in-lieu and on-site parking. Four onsite parking spaces are proposed, including one ADA-
accessible space. These spaces are accessed from the rear alley and located beneath a covered
area associated with the rear addition. Remaining parking mitigation will be met with cash-in-lieu.
Staff supports the parking mitigation as proposed. Providing on-site parking is generally preferred
to cash-in-lieu as it reduces transportation impacts to the surrounding neighborhood. In this case,
80 percent of required parking mitigation will be met on-site, which is a major benefit for tenants
and contributes to the livability and quality of this project. Given the residential use of the
surrounding neighborhood, plenty of on-street parking exists throughout the immediate area.
Lastly, the proximity of this property to the commercial core and public transportation facilities will
further reduce vehicle use for tenants. Again, it should be emphasized that 100 percent of parking
mitigation may be met via cash-in-lieu. The applicant plans to provide 80 percent of required
parking mitigation on-site, which staff considers a benefit to tenants and the surrounding
neighborhood.
In addition to the on-site parking, the applicant has completed the Transportation Impact Analysis
(TIA) for this project and plans to provide a range of Mobility Measures to satisfy the requirements
of the Engineering and Parking Departments. At this point, the applicant has indicated that
All development and redevelopment projects are required to submit a Mobility

year. Staff finds that providing a TDM for one year meets the applicability of this project.
Additionally, bicycle parking will be provided on-site, and other infrastructure improvements will
be made to encourage alternative transportation choices. The TIA is subject to change and will
be assessed at building permit. Staff included a condition in the Resolution prohibiting Mobility
Measures from occupying any of the off-street parking spaces on the property.
Staff finds that this application meets the minimum parking and TIA requirements for the property.

Re: 1020 East Cooper Project
Dear Historic Preservation Commission and Community Development,
We are proud to submit a 100% affordable housing project (“the 1020 Project”) that complies
with underlying zoning for the historic property located at 1020 East Cooper Ave. The property
is located within the City of Aspen’s Residential Multi-Family Zone District (RMF), surrounded by
multi-family buildings, and is approximately 4,379 sf in size 1. The designated historic structure
was formerly the home of columnist and longtime local Su Lum.
Conversion of this property to an affordable housing project aligns with City Council and
community wide goals to provide deed restricted housing within city limits and to preserve
Aspen’s historic fabric for future generations to experience. As stated in the vision statement of
the 2012 Aspen Area Community Plan “we believe that a strong and diverse year-round
community and a viable and healthy local workforce are fundamental cornerstones for the
sustainability of the Aspen Area community.” We propose a five-unit project that fits into the
existing multi-family neighborhood context, meets zoning requirements, and is walking distance
to downtown.
The 1020 Project follows in the footsteps of other affordable housing projects to bring critical
housing infrastructure to our growing town. The success of the affordable housing program in
Aspen strengthens our community fabric and provides meaningful opportunities for our locals to
thrive in the community they call home. The 2019 Greater Roaring Fork Regional Housing Study
directly addresses the impact of affordable housing on local employers and on local employees:
“In a key finding from the research, there is broad agreement among employers of all sizes that
affordable housing is a problem for residents. This opinion is shared by residents. Most employers
feel that affordable/employee housing is a serious issue, with 28% rating it as ‘the most critical
problem in the area,’ and 48% rating it as ‘one of the more serious problems.’”
1 Neighbors have previously questioned the lot size at 1020 East Cooper which was approved by the City of Aspen in 2019
(Bk126 Pg7). A letter from Holland and Hart included as Exhibit 10 provides further confirmation of the 4,379sf lot size.

Demolition.
Proposal
The 1020 Project will restore the historic miner’s cabin and add a new detached building along the
alley to provide a total of five units on the property. The miner’s cabin will be restored, preserved,
and converted into two housing units with a full basement. Two non-historic sheds located partially
in the alley are proposed to be demolished. The new detached building contains three units. Four
surface parking spaces are located off the alley and exterior storage is provided for each unit.

The neighborhood context as defined by the Land Use Code and zone district allowances includes
free-market and deed-restricted affordable housing multi-family residential units and single
family/duplex homes. There are a handful of 19th century landmarks in the immediate area. The
stated purpose of the RMF Zone District is [emphasis added]:
“to provide for the use of land for intensive long-term residential purposes, short term vacation
rentals, and customary accessory uses. Recreational and institutional uses customarily found
in proximity to residential uses are included as conditional uses. Lands in the Residential Multi-
Family (RMF) Zone District are typically those found in the Aspen infill area, within walking
distance of the center of the City or lands on transit routes and other lands with existing
concentrations of attached residential dwellings and mixed attached and detached residential
dwellings.”

Development of affordable housing at 1020 East Cooper directly aligns with the purpose of the
zone district for “intensive long term residential purposes.” The GIS map below shows multi-family
properties and historic landmarks in the vicinity of 1020 East Cooper.
Figure 2: Orange outline identifies landmark property. Star identifies 1020 East Cooper. Note the multi-family properties
in the neighborhood.
The proposed project is contextual to the neighborhood in use and in proportion when compared
to the surrounding three story multi-family buildings directly to the east and west, across the alley,
and across Cooper Avenue.
Affordable Housing
The 1020 Project is a voluntary 100% affordable housing project that requests affordable housing
credits in exchange for creating voluntary deed restricting units. Five housing units are proposed –
three 2-bedroom units and two 3-bedroom units. A breakdown of the unit sizes and locations is
provided in Table 2. A total of 12.75 full time equivalents (FTEs) are generated by the 1020 Project.
The units are proposed to be rentals that are sold to Pitkin County employers to rent to APCHA
qualified employees. According to the Land Use Code and APCHA Standards, category designation
will be finalized at the time of deed restriction by the owner but will be at Category 4 or less.
All units have exterior storage, private outdoor space either on a deck or front porch, and are within
the Aspen Pitkin County Housing Authority (APCHA) size requirements.

Parking
The current single family residence does not have any onsite parking. The 1020 Project is required
to mitigate for five parking spaces. Mitigation can be 100% cash in lieu with no onsite parking
spaces, or a mix of onsite and cash in lieu. Recognizing the importance of a percentage of onsite
parking, four onsite spaces, including an ADA compliant space, are proposed in the carport
accessed off the alley. Carshare memberships will be offered to each unit for their first year to
discourage car ownership, in addition to Wecycle memberships, and onsite bike racks. A welcome
packet with alternative forms of transportation, bike and walking trail maps, and bus schedules will
be provided to tenants. All of these measures discourage car ownership and encourage Aspen’s
robust alternative transportation options. The 1020 Project is conveniently located a few blocks
from downtown, bus stops, and trails.
Historic Preservation
1020 East Cooper has been heavily altered over time - upon physical inspection it appears that
two, simple 19th century miner’s cabins were stitched together in an “L” footprint in the 1890s.
Historic framing, gable roof form, and historic siding are evident inside the building.
There are no clear historic photographs showing the property and historic maps do not include
this neighborhood with the exception of the 1896 Willits Town Map (Figure 3). Historic
newspapers and directories list a number of families residing in the home over the years as far
back as 1889, which shows that 1020 East Cooper was a typical miner’s cabin residence as found
throughout Aspen.
54
Page 6 of 7
1020 East Cooper Project
January 4, 2021
The 1020 Project restores window
openings, clapboard siding, and a
typical open front porch. Historic
structures are found throughout the
neighborhood - the restoration of the
cabin contributes to the character and
pedestrian friendly experience along
Cooper. Historic Preservation Design
Guidelines are addressed in Exhibit 1.
Requests to relocate the landmark to
the 5 feet front setback in accordance
with the Historic Preservation Design
Guidelines, and to demolish the non-
historic and encroaching sheds are
included in Exhibit 1.
Residential Design Standards
Residential Design Standards (RDS) are required for multi-family residential projects that are not
listed on the historic inventory. The new building is subject to RDS and meets all requirements as
demonstrated in Exhibit 6.
Tree
The large spruce tree located within the property boundaries between the rear of the house and
the non-historic sheds has been previously approved for removal by the Parks Department. The
spruce tree that straddles the east property line is not proposed for removal and mitigation unless
consent is received from the Riverside Condominiums because it sits on the shared property line
with roots extending to both properties. A 10’ radius drip line was determined by the City Forester
on July 14, 2020 and is accommodated in the application.
Outreach
Neighborhood engagement is central to the 1020 Project. A project website,
www.1020eastcooperproject.com, was launched in mid-October to serve as a landing site for
information about the project and upcoming outreach events. Before the land use application was
completed, the Applicant mailed project introduction postcards to property owners within 300’
with information about the website, the project team and the upcoming project. The Applicant
also e-mailed this information to neighboring HOAs and other parties who had made comments on
a prior application in earlier hearings. Two online meetings were held between the project team
and neighbors on October 26, 2020 and October 28, 2020 to introduce the project team and to
provide an overview of the project. An online outreach meeting was held on December 1, 2020
with neighbors to review the land use application after it was deemed complete by the City of
Figure 3: 1896 Willits map

Aspen. Neighborhood engagement is planned throughout the land use review process and the
website will be frequently updated through final Certificate of Occupancy.
Thank you for the opportunity to present this important project that balances many community
goals including affordable housing and historic preservation. Together, as a community, we can
address the lack of housing with thoughtful projects throughout town. As stated in the 2012 Aspen
Area Community Plan “the creation of affordable housing is the responsibility of our entire
community, not just government.” Preserving a historic resource as part of an affordable housing
plan is a welcome challenge that results in an authentic project with genuine character, adaptive
reuse of a historic asset, and lights on vitality.
Sincerely,

Exhibit 1
Historic Preservation Reviews
26.415.070. Development involving designated historic property or property within
a historic district.
No building, structure or landscape shall be erected, constructed, enlarged, altered, repaired, relocated or
improved involving a designated historic property or a property located within a Historic District until plans
or sufficient information have been submitted to the Community Development Director and approved in
accordance with the procedures established for their review. An application for a building permit cannot
be submitted without a development order.
b) The procedures for the review of conceptual development plans for major development projects
are as follows:
(1) The Community Development Director shall review the application materials submitted for
conceptual or final development plan approval. If they are determined to be complete, the applicant
will be notified in writing of this and a public hearing before the HPC shall be scheduled. Notice of
the hearing shall be provided pursuant to Section 26.304.060.E.3 Paragraphs a, b and c.
(2) Staff shall review the submittal material and prepare a report that analyzes the project's
conformance with the design guidelines and other applicable Land Use Code sections. This report
will be transmitted to the HPC with relevant information on the proposed project and a
recommendation to continue, approve, disapprove or approve with conditions and the reasons for
the recommendation. The HPC will review the application, the staff analysis report and the evidence
presented at the hearing to determine the project's conformance with the City Historic Preservation
Design Guidelines.
Response: Applicable Design Guidelines are addressed below:
Streetscape
1.1 All projects shall respect the historic development pattern or context of the block, neighborhood or
district.
• Building footprint and location should reinforce the traditional patterns of the neighborhood.
• Allow for some porosity on a site. In a residential project, setback to setback development is
typically uncharacteristic of the historic context. Do not design a project which leaves no useful
open space visible from the street.
Response – The proposed project reinforces the traditional street grid with both buildings perpendicular to
Cooper Street. Open space is provided between the two buildings and in the required setback which comply
with underlying zoning. Visible open space surrounds the historic building, and an existing spruce tree will
be visible directly behind the landmark.
1.2 Preserve the system and character of historic streets, alleys, and ditches.
When HPC input is requested, the following bullet points may be applicable.
57
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
• Retain and preserve the variety and character found in historic alleys, including retaining historic
ancillary buildings or constructing new ones.
• Retain and preserve the simple character of historic ditches. Do not plant flowers or add
landscape.
• Abandoning or re-routing a street in a historic area is generally discouraged.
• Consider the value of unpaved alleys in residential areas.
• Opening a platted right of way which was abandoned or never graded may be encouraged on a
case by case basis.
Response – No changes are proposed in the right of way unless required by Engineering and Parks
Departments. Two non-historic sheds sit in the alley and are proposed to be demolished.
1.3 Remove driveways or parking areas accessed directly from the street if they were not part of the
original development of the site.
• Do not introduce new curb cuts on streets.
• Non-historic driveways accessed from the street should be removed if they can be relocated to
the alley.
Response – n/a.
1.4 Design a new driveway or improve an existing driveway in a manner that minimizes its visual impact.
• If an alley exists at the site, the new driveway must be located off it.
• Tracks, gravel, light grey concrete with minimal seams, or similar materials are appropriate for
driveways on Aspen Victorian properties.
Response – All vehicular access is proposed off the alley.
1.5 Maintain the historic hierarchy of spaces.
• Reflect the established progression of public to private spaces from the public sidewalk to a semi-
public walkway, to a semi private entry feature, to private spaces.
Response – A simple straight walkway is proposed from the sidewalk to the front porch of the historic
buildings. A low fence is contemplated across the front of the property. Access to the rear building is
proposed from the alley.
1.6 Provide a simple walkway running perpendicular from the street to the front entry on residential
projects.
• Meandering walkways are not allowed, except where it is needed to avoid a tree or is typical of
the period of significance.
• Use paving materials that are similar to those used historically for the building style and install
them in the manner that they would have been used historically. For example on an Aspen
Victorian landmark set flagstone pavers in sand, rather than in concrete. Light grey concrete, brick
or red sandstone are appropriate private walkway materials for most landmarks.
58
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
• The width of a new entry sidewalk should generally be three feet or less for residential properties.
A wider sidewalk may be appropriate for an AspenModern property.
Response – A simple walkway perpendicular from the street to the front porch is proposed off the
sidewalk.
1.7 Provide positive open space within a project site.
• Ensure that open space on site is meaningful and consolidated into a few large spaces rather than
many small unusable areas.
• Open space should be designed to support and complement the historic building.
Response – Open space is preserved around the historic building in compliance with the required setbacks
in the RMF zone district. Communal open space is provided between the buildings and beneath the preserved
spruce tree in the east yard.
1.8 Consider stormwater quality needs early in the design process.
• When included in the initial planning for a project, stormwater quality facilities can be better
integrated into the proposal. All landscape plans presented for HPC review must include at least
a preliminary representation of the stormwater design. A more detailed design must be reviewed
and approved by Planning and Engineering prior to building permit submittal.
• Site designs and stormwater management should provide positive drainage away from the
historic landmark, preserve the use of natural drainage and treatment systems of the site, reduce
the generation of additional stormwater runoff, and increase infiltration into the ground.
Stormwater facilities and conveyances located in front of a landmark should have minimal visual
impact when viewed from the public right of way.
• Refer to City Engineering for additional guidance and requirements.
Response – Storm water design is considered as part of the design and a preliminary plan is included in
the drawing set.
1.9 Landscape development on AspenModern landmarks shall be addressed on a case by case basis.
Response – n/a.
1.10 Built-in furnishings, such as water features, fire pits, grills, and hot tubs, that could interfere with or
block views of historic structures are inappropriate.
• Site furnishings that are added to the historic property should not be intrusive or degrade the
integrity of the neighborhood patterns, site, or existing historic landscape.
• Consolidating and screening these elements is preferred.
Response – A grill is potentially proposed between the two buildings. This location does not impact the
historic building.
1.11 Preserve and maintain historically significant landscaping on site, particularly landmark trees and
shrubs.
• Retaining historic planting beds and landscape features is encouraged.
59
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
• Protect historically significant vegetation during construction to avoid damage. Removal of
damaged, aged, or diseased trees must be approved by the Parks Department.
• If a significant tree must be removed, replace it with the same or similar species in coordination
with the Parks Department.
• The removal of non-historic planting schemes is encouraged.
• Consider restoring the original landscape if information is available, including original plant
materials.
Response – The spruce tree in the east side yard is proposed to remain based on neighbor comments.
1.12 Provide an appropriate context for historic structures. See diagram.
• Simplicity and restraint are required. Do not overplant a site, or install a landscape which is
overtextured or overly complex in relationship to the historic resource, particularly in Zone A. In
Zone A, new planting shall be species that were used historically or species of similar attributes.
• In areas immediately adjacent to the landmark, Zone A and Zone B, plants up 42” in height, sod,
and low shrubs are often appropriate.
• Contemporary planting, walls and other features are not appropriate in Zone A. A more
contemporary landscape may surround new development or be located in the rear of the
property, in Zone C.
• Do not cover areas which were historically unpaved with hard surfaces, except for a limited patio
where appropriate.
• Where residential structures are being adapted to commercial use, proposals to alter the
landscape will be considered on a case-by-case basis. The residential nature of the building must
be honored.
• In the case of a historic landmark lot split, careful consideration should be given so as not to over
plant either property, or remove all evidence of the landscape characteristics from before the
property was divided.
• Contemporary landscapes that highlight an AspenModern architectural style are encouraged.
Response – Simple landscaping is proposed around the historic structure and will be more developed for
Final Review.
1.13 Additions of plant material to the landscape that could interfere with or block views of historic
structures are inappropriate.
• Low plantings and ground covers are preferred.
• Do not place trees, shrubs, or hedgerows in locations that will obscure, damage, or block
significant architectural features or views to the building. Hedgerows are not allowed as fences.
• Consider mature canopy size when planting new trees adjacent to historic resources. Planting
trees too close to a landmark may result in building deteriorate or blocked views and is
inappropriate.
• Climbing vines can damage historic structures and are not allowed.
Response – Sod and low plants are contemplated around the landmark to not obscure historic
characteristics and to avoid accelerating deterioration of historic material.
60
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
1.14 Minimize the visual impacts of landscape lighting.
• Landscape and pathway lighting is not permitted in Zone A (refer to diagram) on Aspen Victorian
properties unless an exception is approved by HPC based on safety considerations.
• Landscape, driveway, and pathway lighting on AspenModern properties is addressed on a case-
by-case basis.
• Landscape light fixtures should be carefully selected so that they are compatible with the building,
yet recognizable as a product of their own time.
• Driveway lighting is not permitted on Aspen Victorian properties.
• Landscape uplighting is not allowed.
Response – Landscape lighting is not proposed at this time.
1.15 Preserve original fences.
• Fences which are considered part of the historic significance of a site should not be moved,
removed, or inappropriately altered.
• Replace only those portions of a historic fence that are deteriorated beyond repair.
• Replacement elements must match the existing.
Response – The existing fence is not original and is proposed to be removed and possibly replaced.
1.16 When possible, replicate a missing historic fence based on photographic evidence.
Response – n/a.
1.17 No fence in the front yard is often the most appropriate solution.
• Reserve fences for back yards and behind street facing façades, as the best way to preserve the
character of a property.
Response – A low picket fence is contemplated in the front yard to define the property and frame the
historic building.
1.18 When building an entirely new fence, use materials that are appropriate to the building type and
style.
• The new fence should use materials that were used on similar properties during the period of
significance.
• A wood fence is the appropriate solution in most locations.
• Ornate fences, including wrought iron, may create a false history are not appropriate for Aspen
Victorian landmarks unless there is evidence that a decorative fence historically existed on the
site.
• A modest wire fence was common locally in the early 1900s and is appropriate for Aspen Victorian
properties. This fence type has many desirable characteristics including transparency, a low
height, and a simple design. When this material is used, posts should be simply detailed and not
oversized.
61
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
Response – Side yard fencing is not proposed at this time; however, the applicant is in discussions with
the neighboring properties to understand their preference for fencing along the shared lot lines.
1.19 A new fence should have a transparent quality, allowing views into the yard from the street.
• A fence that defines a front yard must be low in height and transparent in nature.
• For a picket fence, spacing between the pickets must be a minimum of 1/2 the width of the picket.
• For Post-WWII properties where a more solid type of fence may be historically appropriate,
proposals will be reviewed on a case-by-case basis.
• Fence columns or piers should be proportional to the fence segment.
Response – The low picket fence along the front of the property meets these requirements and is
transparent as defined above.
1.20 Any fence taller than 42” should be designed so that it avoids blocking public views of important
features of a designated building.
• A privacy fence should incorporate transparent elements to minimize the possible visual impacts.
Consider staggering the fence boards on either side of the fence rail. This will give the appearance
of a solid plank fence when seen head on. Also consider using lattice, or other transparent
detailing on the upper portions of the fence.
• A privacy fence should allow the building corners and any important architectural features that
are visible from the street to continue to be viewed.
• All hedgerows (trees, shrub bushes, etc.) are prohibited in Zones A and B.
Response – The fence along the front of the property is less than 42” in height.
1.21 Preserve original retaining walls
• Replace only those portions that are deteriorated beyond repair. Any replacement materials
should match the original in color, texture, size and finish.
• Painting or covering a historic masonry retaining wall or covering is not allowed.
• Increasing the height of a retaining wall is inappropriate.
Response – n/a.
1.22 When a new retaining wall is necessary, its height and visibility should be minimized.
• All wall materials, including veneer and mortar, will be reviewed on a case by case basis and should
be compatible with the palette used on the historic structure.
Response – n/a.
1.23 Re-grading the site in a manner that changes historic grade is generally not allowed and will be
reviewed on a case by case basis.
Response – Minor grading of the site is proposed to ensure proper drainage away from the buildings.
Significant regrading is not proposed.
62
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
1.24 Preserve historically significant landscapes with few or no alterations.
• An analysis of the historic landscape and an assessment of the current condition of the landscape
should be done before the beginning of any project.
• The key features of the historic landscape and its overall design intent must be preserved.
Response – n/a. This property does not have a recognized historically significant landscape.
1.25 New development on these sites should respect the historic design of the landscape and its built
features.
• Do not add features that damage the integrity of the historic landscape.
• Maintain the existing pattern of setbacks and siting of structures.
• Maintain the historic relationship of the built landscape to natural features on the site.
• All additions to these landscapes must be clearly identifiable as recent work.
• New artwork must be subordinate to the designed landscape in terms of placement, height,
material, and overall appearance. Place new art away from significant landscape features.
• Avoid installing utility trenches in cultural landscapes if possible.
Response – n/a. This property does not have a recognized historically significant landscape.
1.26 Preserve the historic circulation system.
• Minimize the impact of new vehicular circulation.
• Minimize the visual impact of new parking.
• Maintain the separation of pedestrian and vehicle which occurred historically.
Response – Parking is located off the alley.
1.27 Preserve and maintain significant landscaping on site.
• Protect established vegetation during any construction.
• If any tree or shrub needs to be removed, replace it with the same or similar species.
• New planting should be of a species used historically or a similar species.
• Maintain and preserve any gardens and/or ornamental planting on the site.
• Maintain and preserve any historic landscape elements.
Response – The preserved spruce tree in the east yard will be protected during construction in accordance
with the City of Aspen Parks Department regulations.
Restoration
Materials
2.1 Preserve original building materials.
• Do not remove siding that is in good condition or that can be repaired in place.
63
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
• Masonry features that define the overall historic character, such as walls, cornices, pediments,
steps and foundations, should be preserved.
• Avoid rebuilding a major portion of an exterior wall that could be repaired in place.
Reconstruction may result in a building which no longer retains its historic integrity.
• Original AspenModern materials may be replaced in kind if it has been determined that the
weathering detracts from the original design intent or philosophy.
2.2 The finish of materials should be as it would have existed historically.
• Masonry naturally has a water-protective layer to protect it from the elements. Brick or stone
that was not historically painted shall not be painted.
• If masonry that was not painted historically was given a coat of paint at some more recent time,
consider removing it, using appropriate methods.
• Wood should be painted, stained or natural, as appropriate to the style and history of the building.
2.3 Match the original material in composition, scale and finish when replacing materials on primary
surfaces.
• If the original material is wood clapboard for example, then the replacement material must be
wood as well. It should match the original in size, and the amount of exposed lap and finish.
• Replace only the amount required. If a few boards are damaged beyond repair, then only those
should be replaced, not the entire wall. For AspenModern buildings, sometimes the replacement
of a larger area is required to preserve the integrity of the design intent.
2.4 Do not use synthetic materials as replacements for original building materials.
• Original building materials such as wood siding and brick should not be replaced with synthetic
materials.
2.5 Covering original building materials with new materials is inappropriate.
• Regardless of their character, new materials obscure the original, historically significant material.
• Any material that covers historic materials may also trap moisture between the two layers. This
will cause accelerated deterioration to the historic material which may go unnoticed.
2.6 Remove layers that cover the original material.
• Once the non-historic siding is removed, repair the original, underlying material.
Response – Existing conditions beneath the vinyl siding do not show historic siding. Historic siding is found
in the interior of the building where the two historic buildings were stitched together. This siding will be
used to dimension new siding for the exterior of the historic building for discussion during Final Review.
Windows
3.1 Preserve the functional and decorative features of a historic window.
• Features important to the character of a window include its frame, sash, muntins/mullions, sills,
heads, jambs, moldings, operations, and groupings of windows.
64
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
• Repair frames and sashes rather than replacing them.
• Preserve the original glass. If original Victorian era glass is broken, consider using restoration glass
for the repair.
3.2 Preserve the position, number, and arrangement of historic windows in a building wall.
• Enclosing a historic window is inappropriate.
• Do not change the size of an original window opening.
3.3 Match a replacement window to the original in its design.
• If the original is double-hung, then the replacement window must also be double-hung. If the
sash have divided lights, match that characteristic as well.
3.4 When replacing an original window, use materials that are the same as the original.
3.5 Preserve the size and proportion of a historic window opening.
• Changing the window opening is not permitted.
• Consider restoring an original window opening that was enclosed in the past.
3.6 Match, as closely as possible, the profile of the sash and its components to that of the original
window.
• A historic window often has a complex profile. Within the window’s casing, the sash steps back to
the plane of the glazing (glass) in several increments. These increments, which individually only
measure in eighths or quarters of inches, are important details. They distinguish the actual
window from the surrounding plane of the wall.
• The historic profile on AspenModern properties is typically minimal.
3.7 Adding new openings on a historic structure is generally not allowed.
• Greater flexibility in installing new windows may be considered on rear or secondary walls.
• New windows should be similar in scale to the historic openings on the building, but should in
some way be distinguishable as new, through the use of somewhat different detailing, etc.
• Preserve the historic ratio of window openings to solid wall on a façade.
• Significantly increasing the amount of glass on a character defining façade will negatively affect
the integrity of a structure.
3.8 Use a storm window to enhance energy conservation rather than replace a historic window.
• Install a storm window on the interior, when feasible. This will allow the character of the original
window to be seen from the public way.
• If a storm window is to be installed on the exterior, match the sash design and material of the original
window. It should fit tightly within the window opening without the need for sub-frames or panning
65
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
around the perimeter. A storm window should not include muntins unless necessary for structure.
Any muntin should be placed to match horizontal or vertical divisions of the historic window.
Response – No original or historic windows exist. Traditional double hung windows are proposed in the
historic building. Framing within the historic building does not clearly demonstrate original openings, but
provides some insight that informs the proposed window locations.
Doors
4.1 Preserve historically significant doors.
• Maintain features important to the character of a historic doorway. These include the door, door
frame, screen door, threshold, glass panes, paneling, hardware, detailing, transoms and flanking
sidelights.
• Do not change the position and function of original front doors and primary entrances.
• If a secondary entrance must be sealed shut, any work that is done must be reversible so that the
door can be used at a later time, if necessary. Also, keep the door in place, in its historic position.
• Previously enclosed original doors should be reopened when possible.
4.2 Maintain the original size of a door and its opening.
• Altering its size and shape is inappropriate. It should not be widened or raised in height.
4.3 When a historic door or screen door is damaged, repair it and maintain its general historic
appearance.
4.4 When replacing a door or screen door, use a design that has an appearance similar to the original
door or a door associated with the style of the building.
• A replica of the original, if evidence exists, is the preferred replacement.
• A historic door or screen door from a similar building also may be considered.
• Simple paneled doors were typical for Aspen Victorian properties.
• Very ornate doors, including stained or leaded glass, are discouraged, unless photographic
evidence can support their use.
4.5 Adding new doors on a historic building is generally not allowed.
• Place new doors in any proposed addition rather than altering the historic resource.
• Greater flexibility in installing a door in a new location may be considered on rear or secondary
walls.
• A new door in a new location should be similar in scale and style to historic openings on the
building and should be a product of its own time.
• Preserve the historic ratio of openings to solid wall on a façade. Significantly increasing the
openings on a character defining façade negatively affects the integrity of a structure.
66
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
4.6 If energy conservation and heat loss are concerns, use a storm door instead of replacing a historic
entry door.
• Match the material, frame design, character, and color of the primary door.
• Simple features that do not detract from the historic entry door are appropriate for a new storm
door.
• New screen doors should be in character with the primary door.
4.7 Preserve historic hardware.
• When new hardware is needed, it must be in scale with the door and appropriate to the style of
the building.
• On Aspen Victorian properties, conceal any modern elements such as entry key pads.
Response – There are no historic doors on this property. A simple front door is proposed facing Cooper
Avenue.
Porch
5.1 Preserve an original porch or balcony.
• Replace missing posts and railings when necessary. Match the original proportions, material and
spacing of balusters.
• Expanding the size of a historic porch or balcony is inappropriate.
5.2 Avoid removing or covering historic materials and details.
• Removing an original balustrade, for example, is inappropriate.
5.3 Enclosing a porch or balcony is not appropriate.
• Reopening an enclosed porch or balcony is appropriate.
5.4 If reconstruction is necessary, match the original in form, character and detail.
• Match original materials.
• When reconstructing an original porch or balcony without historic photographs, use dimensions
and characteristics found on comparable buildings. Keep style and form simple with minimal, if
any, decorative elements.
5.5 If new steps are to be added, construct them out of the same primary materials used on the original,
and design them to be in scale with the porch or balcony
• Steps should be located in the original location.
• Step width should relate to the scale of entry doors, spacing between posts, depth of deck, etc.
• Brick, red sandstone, grey concrete, or wood are appropriate materials for steps.
67
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
5.6 Avoid adding handrails or guardrails where they did not exist historically, particularly where visible
from the street.
• If handrails or guardrails are needed according to building code, keep their design simple in
character and different from the historic detailing on the porch or balcony.
Response – A simple traditional open front porch with one step is proposed facing Cooper Avenue. Framing
within the historic building is unclear as to whether the front entry was an open porch or enclosed. An open
porch is proposed at this time since it was a traditional characteristic of 19th century miner’s cabins, and an
open porch aligns with the 1896 Willits map L shaped footprint.
Architectural Details
6.1 Preserve significant architectural features.
• Repair only those features that are deteriorated.
• Patch, piece-in, splice, or consolidate to repair the existing materials, using recognized
preservation methods whenever possible.
• On AspenModern properties, repair is preferred, however, it may be more important to preserve
the integrity of the original design intent, such as crisp edges, rather than to retain heavily
deteriorated material.
6.2 When disassembly of a historic element is necessary for its restoration, use methods that minimize
damage to the original material.
• Document its location so it may be repositioned accurately. Always devise methods of replacing
the disassembled material in its original configuration.
6.3 Remove only the portion of the detail that is deteriorated and must be replaced.
• Match the original in composition, scale, and finish when replacing materials or features.
• If the original detail was made of wood, for example, then the replacement material should be
wood, when feasible. It should match the original in size and finish.
6.4 Repair or replacement of missing or deteriorated features are required to be based on original
designs.
• The design should be substantiated by physical or pictorial evidence to avoid creating a
misrepresentation of the building’s heritage.
• When reconstruction of an element is impossible because there is no historical evidence, develop
a compatible new design that is a simplified interpretation of the original, and maintains similar
scale, proportion and material.
6.5 Do not guess at “historic” designs for replacement parts.
• Where scars on the exterior suggest that architectural features existed, but there is no other
physical or photographic evidence, then new features may be designed that are similar in character
to related buildings.
68
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
• Using ornate materials on a building or adding new conjectural detailing for which there is no
documentation is inappropriate.
Response – Original architectural details are lost with the exception of the gable end inside the interior of
the historic building. Any relevant historic details on the gable end will be used on the historic building
for review during Final Design. All other details will be simple, traditional, and similar to features found
on other 19th century miner’s cabins.
Roof
7.1 Preserve the original form of a roof.
• Do not alter the angle of a historic roof. Preserve the orientation and slope of the roof as seen from
the street.
• Retain and repair original and decorative roof detailing.
• Where the original roof form has been altered, consider restoration.
7.2 Preserve the original eave depth.
• Overhangs contribute to the scale and detailing of a historic resource.
• AspenModern properties typically have very deep or extremely minimal overhangs that are key
character defining features of the architectural style.
7.3 Minimize the visual impacts of skylights and other rooftop devices.
• Skylights and solar panels are generally not allowed on a historic structure. These elements may
be appropriate on an addition.
7.4 New vents should be minimized, carefully, placed and painted a dark color.
• Direct vents for fireplaces are generally not permitted to be added on historic structures.
• Locate vents on non-street facing facades.
• Use historic chimneys as chases for new flues when possible.
7.5 Preserve original chimneys, even if they are made non-functional.
• Reconstruct a missing chimney when documentation exists.
7.6 A new dormer should remain subordinate to the historic roof in scale and character.
• A new dormer is not appropriate on a primary, character defining façade.
• A new dormer should fit within the existing wall plane. It should be lower than the ridgeline and
set in from the eave. It should also be in proportion with the building.
• The mass and scale of a dormer addition must be subordinate to the scale of the historic building.
• While dormers improve the livability of upper floor spaces where low plate heights exist, they also
complicate the roof and may not be appropriate on very simple structures.
69
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
New Building
• Dormers are not generally not permitted on AspenModern properties since they are not
characteristics of these building styles.
7.7 Preserve original roof materials.
• Avoid removing historic roofing material that is in good condition. When replacement is
necessary, use a material that is similar to the original in both style as well as physical qualities
and use a color that is similar to that seen historically.
7.8 New or replacement roof materials should convey a scale, color and texture similar to the original.
• If a substitute is used, such as composition shingle, the roof material should be earth tone and
have a matte, non-reflective finish.
• Flashing should be in scale with the roof material.
• Flashing should be tin, lead coated copper, galvanized or painted metal and have a matte, non-
reflective finish.
• Design flashing, such as drip edges, so that architectural details are not obscured.
• A metal roof is inappropriate for an Aspen Victorian primary home but may be appropriate for a
secondary structure from that time period.
• A metal roof material should have a matte, non-reflective finish and match the original seaming.
7.9 Avoid using conjectural features on a roof.
• Adding ornamental cresting, for example, where there is no evidence that it existed, creates a
false impression of the building’s original appearance, and is inappropriate.
7.10 Design gutters so that their visibility on the structure is minimized to the extent possible.
• Downspouts should be placed in locations that are not visible from the street if possible, or in
locations that do not obscure architectural detailing on the building.
• The material used for the gutters should be in character with the style of the building.
Response – The existing roof form is proposed to remain as is. Composite shingles that are low
maintenance and similar in style to wood shingles are proposed to replace the existing asphalt roof.
Gutters, downspouts, and roof penetrations will be presented at Final Design Review.
Building Placement
11.1 Orient the new building to the street.
• AspenVictorian buildings should be arranged parallel to the lot lines, maintaining the traditional
grid pattern.
• AspenModern alignments shall be handled case by case.
70
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
• Generally, do not set the new structure forward of the historic resource. Alignment of their front
setbacks is preferred. An exception may be made on a corner lot or where a recessed siting for
the new structure is a better preservation outcome.
Response – The new building is located behind the landmark and along the alley. It is parallel to the lot
lines which is consistent with the traditional grid pattern. Setback variances are not requested for the new
building.
Mass and Scale
11.2 In a residential context, clearly define the primary entrance to a new building by using a front
porch.
• The front porch shall be functional, and used as the means of access to the front door.
• A new porch must be similar in size and shape to those seen traditionally.
Response – The entrance to the new building is defined by a front porch at the street facing ground level
unit. The small size and one story nature of the proposed porch is similar to traditional front porches. A
small porch is proposed on the west elevation attached to an existing non-historic addition to the
landmark. This small porch provides a sheltered entrance and access to the rear unit in the historic
building.
11.3 Construct a new building to appear similar in scale and proportion with the historic buildings on a
parcel.
• Subdivide larger masses into smaller “modules” that are similar in size to the historic buildings
on the original site.
• Reflect the heights and proportions that characterize the historic resource.
Response – The proposed L shaped footprint of the new building directly references the historic building’s
footprint. The prominent gable roof form has a similar pitch to the historic building. Material changes
between the ground level and upper levels break up the massing, and dormers along the east and west
facades add living space for the upper level unit while maintaining a prominent gable form. Sliding wood
shutters are proposed to add interest and to break up the façade of the building, and vertical wood board
and batten on the upper levels of the wood building add depth and dimension to the front façade.
Galvanized metal siding is proposed for the first level and as accents on the upper levels to add interest
to the east and west facades that face the neighboring multi-family buildings.
The set back of the new building behind the historic building and site green space very much reduces the
perception and appearance of mass and scale from the sidewalk. See also response to 11.4 below.
A bump out is proposed at the southwest corner of the landmark, in a non-historic location, to allow a
small accessible bathroom at grade which makes this unit visitable under ADA standards. Two small
exterior storage units are proposed on the west elevation of the landmark to provide additional storage.
71
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
11.4 Design a front elevation to be similar in scale to the historic building.
• The primary plane of the front shall not appear taller than the historic structure.
Response – The front elevation of the new building is taller than the 15’ 4” one story historic building.
Creative design solutions are proposed to reduce the perception of this height difference. The 10 feet
distance between new and historic construction pushes the new building toward the alley. The building
sits at the 5 feet setback line, and could be pushed further back toward the alley at HPC’s direction to
increase this distance. The new building contextually sits between three story buildings to the east and
west of the 1020 property, and successfully completes the streetscape in this high density residential
neighborhood while preserving a one story historic cabin at the front of the property.
Decks and open stairs are proposed behind the landmark to break up the mass and to provide relief to
the Riverside Condominiums. The preservation of the spruce tree on the shared lot line between 1020
Project and Riverside provides a natural buffer between the properties; however, it also limits the ability
to spread out and step up massing behind the landmark.
11.5 The intent of the historic landmark lot split is to remove most of the development potential from
the historic resource and place it in the new structure.
• This should be kept in mind when determining how floor area will be allocated between
structures proposed as part of a lot split.
Response – A historic lot split is not proposed on this property; however, a new detached building is
proposed that removes development pressure from the landmark into the new construction.
11.6 Design a new structure to be recognized as a product of its own time.
• Consider these three aspects of a new building; form, materials, and fenestration. A project
must relate strongly to the historic resource in at least two of these elements. Departing from
the historic resource in one of these categories allows for creativity and a contemporary design
response.
• When choosing to relate to building form, use forms that are similar to the historic resource.
• When choosing to relate to materials, use materials that appear similar in scale and finish to
those used historically on the site and use building materials that contribute to a traditional
sense of human scale.
• When choosing to relate to fenestration, use windows and doors that are similar in size and
shape to those of the historic resource.
Response – The new building relates to building form and material application. Windows are rectangular
but are contemporary along the front (south) elevation. Building form relates to the landmark in
footprint, roof form, and roof pitch. Wood is proposed as the primary material to relate to the landmark.
The style and application of wood siding recalls historic woodsheds along Aspen’s alleys and is similar to
the some of the historic wood found within the walls of the 1020 landmark. Durability and low
maintenance are a primary consideration in the selection of weathered wood and galvanized metal on
the rear building.
11.7 The imitation of older historic styles is discouraged.
72
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
• This blurs the distinction between old and new buildings.
• Overall, details shall be modest in character.
Response – The new building is clearly a product of its own time while simultaneously supporting and
highlighting the historic landmark. Details are subtle in nature and materials are durable to limit capital
expenses for the affordable housing residents.
26.415.080. Demolition of designated historic properties or properties within a
historic district.
It is the intent of this Chapter to preserve the historic and architectural resources that have demonstrated
significance to the community. Consequently no demolition of properties designated on the Aspen
Inventory of Historic Landmark Site and Structures or properties within a Historic District will be allowed
unless approved by the HPC in accordance with the standards set forth in this Section.
4. The HPC shall review the application, the staff report and hear evidence presented by the property
owners, parties of interest and members of the general public to determine if the standards for
demolition approval have been met. Demolition shall be approved if it is demonstrated that the
application meets any one of the following criteria:
a) The property has been determined by the City to be an imminent hazard to public safety and
the owner/applicant is unable to make the needed repairs in a timely manner,
b) The structure is not structurally sound despite evidence of the owner's efforts to properly
maintain the structure,
c) The structure cannot practically be moved to another appropriate location in Aspen or
d) No documentation exists to support or demonstrate that the property has historic,
architectura l, archaeological, engineering or cultural significance and
Additionally, for approval to demolish, all of the following criteria must be met:
a) The structure does not contribute to the significance of the parcel or Historic District in which it
is located and
b) The loss of the building, structure or object would not adversely affect the integrity of the
Historic District or its historic, architectural or aesthetic relationship to adjacent designated
properties and
c) Demolition of the structure will be inconsequential to the historic preservation needs of the
area.
Response – Two non-historic sheds are located partly on the 1020 property and partly within the alley. The
sheds are not shown on the Willits Map or any other 19th century aerial photographs. As such, the two
sheds are not related to the period of significance of the miner’s cabin and are requested to be demolished.
26.415.090. Relocation of designated historic properties.
The intent of this Chapter is to preserve designated historic properties in their original locations as much
of their significance is embodied in their setting and physical relationship to their surroundings as well as
73
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
their association with events and people with ties to particular site. However, it is recognized that
occasionally the relocation of a property may be appropriate as it provides an alternative to demolition or
because it only has a limited impact on the attributes that make it significant.
C. Standards for the relocation of designated properties. Relocation for a building, structure or object
will be approved if it is determined that it meets any one of the following standards:
1. It is considered a noncontributing element of a historic district and its relocation will not affect the
character of the historic district; or
2. It does not contribute to the overall character of the historic district or parcel on which it is located
and its relocation will not have an adverse impact on the Historic District or property; or
3. The owner has obtained a certificate of economic hardship; or
4. The relocation activity is demonstrated to be an acceptable preservation method given the
character and integrity of the building, structure or object and its move will not adversely affect the
integrity of the Historic District in which it was originally located or diminish the historic,
architectural or aesthetic relationships of adjacent designated properties; and
Additionally, for approval to relocate all of the following criteria must be met:
1. It has been determined that the building, structure or object is capable of withstanding the physical
impacts of relocation;
2. An appropriate receiving site has been identified; and
3. An acceptable plan has been submitted providing for the safe relocation, repair and preservation of
the building, structure or object including the provision of the necessary financial security.
Response – The historic landmark is proposed to be stabilized and moved to the 5 feet front setback toward
Cooper Avenue. The landmark is not part of a historic district and its relocation forward provides better
visibility of the restored miner’s cabin along Cooper Avenue. The context and setting of the landmark have
significantly changed over time with three story large condominium buildings to the east and west of the
property. Pulling the landmark forward gives it street presence and positively contributes to the streetscape.
The standard $30,000 letter of credit or similar form of financial assurance is acceptable to the owner to
ensure safe relocation of the landmark.
Design guidelines are addressed below:
9.1 Developing a basement by underpinning and excavating while the historic structure remains in place
may help to preserve the historic fabric.
• This activity will require the same level of documentation, structural assessment, and posting of
financial assurances as a building relocation.
Response – n/a. The historic building is proposed to be relocated on the site.
9.2 Proposals to relocate a building will be considered on a case-by-case basis.
74
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
• In general, on-site relocation has less of an impact on individual landmark structures than those
in a historic district.
• In a district, where numerous adjacent historic structures may exist, the way that buildings were
placed on the site historically, and the open yards visible from the street are characteristics that
should be respected in new development.
• Provide a figure ground study of the surrounding parcels to demonstrate the effects of a building
relocation.
• In some cases, the historic significance of the structure, the context of the site, the construction
technique, and the architectural style may make on-site relocation too impactful to be
appropriate. It must be demonstrated that on-site relocation is the best preservation alternative
in order for approval to be granted.
• If relocation would result in the need to reconstruct a substantial area of the original exterior
surface of the building above grade, it is not an appropriate preservation option.
Response – Relocating the house forward on the lot brings the landmark into closer relationship to buildings
along the block that meet the required 5 feet setback. A more prominent location on the property highlights
the landmark in a high density neighborhood.
9.3 Site a relocated structure in a position similar to its historic orientation.
• It must face the same direction and have a relatively similar setback. In general, a forward
movement, rather than a lateral movement is preferred. HPC will consider setback variations
where appropriate.
• A primary structure may not be moved to the rear of the parcel to accommodate a new building in
front of it.
• Be aware of potential restrictions against locating buildings too close to mature trees. Consult with
the City Forester early in the design process. Do not relocate a building so that it becomes obscured
by trees.
Response – The structure is proposed to be moved to comply with the 5 feet side setbacks and the 5 feet
front yard setback. The perpendicular orientation of the building to Cooper Avenue is maintained which
reinforces the traditional street grid and traditional siting of historic buildings.
9.4 Position a relocated structure at its historic elevation above grade.
• Raising the finished floor of the building slightly above its original elevation is acceptable if needed
to address drainage issues. A substantial change in position relative to grade is inappropriate.
• Avoid making design decisions that require code related alterations which could have been avoided.
In particular, consider how the relationship to grade could result in non-historic guardrails, etc.
Response – There are challenging grades on the property, as noted on the improvement survey. A slight
increase in height is proposed for the landmark to accommodate a single step to the front porch and to
promote positive drainage away from the historic resource.
75
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
9.5 A new foundation shall appear similar in design and materials to the historic foundation.
• On modest structures, a simple foundation is appropriate. Constructing a stone foundation on a
miner’s cottage where there is no evidence that one existed historically is out of character and is
not allowed.
• Exposed concrete or painted metal flashing are generally appropriate.
• Where a stone or brick foundation existed historically, it must be replicated, ideally using stone
salvaged from the original foundation as a veneer. The replacement must be similar in the cut of
the stone and design of the mortar joints.
• New AspenModern foundations shall be handled on a case by case basis to ensure preservation
of the design intent.
Response – The new foundation will be exposed concrete or painted metal flashing.
9.6 Minimize the visual impact of lightwells.
• The size of any lightwell that faces a street should be minimized.
• Lightwells must be placed so that they are not immediately adjacent to character defining
features, such as front porches.
• Lightwells must be protected with a flat grate, rather than a railing or may not be visible from a
street.
• Lightwells that face a street must abut the building foundation and generally may not “float” in
the landscape except where they are screened, or on an AspenModern site.
Response – Lightwells are the minimum 3 x 3 size for egress, and are minimized to the greatest extend
possible while still provided natural light to below grade bedrooms.
9.7 All relocations of designated structures shall be performed by contractors who specialize in moving
historic buildings, or can document adequate experience in successfully relocating such buildings.
• The specific methodology to be used in relocating the structure must be approved by the HPC.
• During the relocation process, panels must be mounted on the exterior of the building to protect
existing openings and historic glass. Special care shall be taken to keep from damaging door and
window frames and sashes in the process of covering the openings. Significant architectural
details may need to be removed and securely stored until restoration.
• The structure is expected to be stored on its original site during the construction process.
Proposals for temporary storage on a different parcel will be considered on a case by case basis
and may require special conditions of approval.
• A historic resource may not be relocated outside of the City of Aspen.
Response – A letter from a licensed engineer is included as Exhibit 2. A house mover has inspected the
historic building and proposed relocation and is confident in a successful relocation.
76
Exhibit 1
HP Reviews (Dec. 23, 2020)
1020 East Cooper Project
9.8 Proposals to relocate a building to a new site are highly discouraged.
• Permanently relocating a structure from where it was built to a new site is only allowed for special
circumstances, where it is demonstrated to be the only preservation alternative.
Response – n/a.

Re: 1020 East Cooper Project
Aspen, Colorado
Dear Collin,
This is in regards to proposed improvements to the existing residence at 1020 East Cooper Street in
Aspen. Current plans by your office indicate that the existing building is to be moved on the site to
facilitate construction of a full basement and building additions placed to the north. On May 30,
2019 I visited the project site to observe and review the existing residence in regards to its
soundness, ability to withstand the physical move and its rehabilitation needs after the move.
The existing residence is a single story wood framed structure with gable roofs and a framed floor
over a shallow crawl space. I understand that the south portion of the residence including the living
room and two bedrooms is the original construction and is considered historic. The north portion
including the kitchen, dining and an additional bedroom are a subsequent addition to the original.
The addition appears to have a concrete foundation. The crawlspace below the original construction
was not accessible. Portions of the building may have experienced some settlement considering the
limited function of some doors and windows.
Based on observations the existing building structure appears to be basically sound and should be
able to withstand the physical move. I understand that the Covered Patio along the north side of the
building is to be demolished prior to the move. The physical move of the building should be
conducted by a qualified building mover with appropriate experience in stabilizing and moving
similar structures.

PRE-APPLICATION CONFERENCE SUMMARY
PLANNER: Amy Simon, amy.simon@cityofaspen.com
DATE: August 27, 2019
PROJECT LOCATION: 1020 E. Cooper Avenue
REQUEST: Major Development, Demolition, Relocation, Growth Management, Affordable Housing Credits
REPRESENTATIVE: Sara Adams, sara@bendonadams.com
DESCRIPTION: 1020 E. Cooper is a landmark designated property which contains a heavily altered Victorian
era single family home. Two outbuildings, date of construction unknown, sit at the rear of the site. The lot
is 4,379 square feet in size and is located in the RMF zone district. Because the minimum lot area for the
zone district is 6,000 square feet, 1020 E. Cooper is considered to be a non-conforming lot of record.
Landmark designation permits the site to be developed with any of the allowed RMF uses, according to
Section 26.312 of the Municipal Code.
A potential purchaser in interested in creating multi-family housing and affordable housing credits. This will
require review by the Historic Preservation Commission which is likely to include a proposal to demolish the
sheds at the rear of the site, to demolish non-historic additions to the miner’s cottage, to re-position the
miner’s cottage and to expand above and below grade. Setback variations may be requested. A tree that
straddles the east property line is to be protected and retained in the redevelopment.
Please refer to the RMF zone district for guidance on dimensional requirements. The parking requirement is
1 parking unit per dwelling unit which may be provided as a mix of on-site parking, TIA measures and cash-
in-lieu. At least one on-site space would likely need to be accessible and approximately twice the width of
a standard parking space. In addition, the alley frontage will need to include adequate trash and recycling
storage and utilities.
Prior to the preparation of a recommendation to HPC, staff will refer the application to other City
Departments for comments and proposed conditions of approval. The applicant will be required to prepare
a Transportation Impact Analysis for Engineering Review.
The first review step will be Conceptual design, Demolition, Relocation, Variations, Growth Management,
and Affordable Housing Credits. Following Conceptual approval, staff will inform Council of HPC’s
decision, allowing them the opportunity to “call up” any aspects of the approval that they find require
additional discussion. This is standard practice for all significant reviews before HPC.
The last step is Final design review.

Re: Pending Historic Preservation Commission Application for 1020 E. Cooper
Avenue, Aspen, Colorado 8161, aka the East 13.79’ of Lot O and all of Lot P,
East Aspen Addition to City of Aspen
Dear Amy and Jim:
Holland & Hart LLP represents 1020 Cooper LLC, the owner of the above referenced
property (the “Subject Property”).
This letter is in response to the comments contained in the September 8, 2020 letter
submitted by counsel for Cooper Avenue Victorian Condominium unit owner Bukk Carleton
relative to the Lot Line Adjustment/Subdivision Exemption Plat for the Subject Property,
recorded on October 8, 2019 at Plat Book 126 at Page 7 under Reception No. 659373 of the
Pitkin County real property records (the “Boundary Adjustment Plat”).
By way of background, the prior owner of the Subject Property, longtime Aspen
journalist Su Lum, acquired the Subject Property in 1972 and owned it until her death in 2017.
The 3.79’ wide strip of land that serves as the western portion of the Subject Property (the “Strip
of Land”) was the subject of a quiet title action brought by Ms. Lum against the Cooper Avenue
Victorian Condominiums which settled in 2006, resulting in the owners of all five condominium
units within the Cooper Avenue Victorian Condominiums and Cooper Avenue Victorian
Condominium Association, Inc. quit claiming their interests in the Strip of land to Ms. Lum.
As part of the disposition of the Subject Property from the Estate of Su Lum, 1020
Cooper LLC processed with the City of Aspen the Boundary Adjustment Plat to confirm the

inclusion of the Strip of Land together with the eastern 10’ of Lot O within the historically
recognized boundaries of the Subject Property.
The Boundary Adjustment Plat process was specifically prescribed by Community
Development office staff and an application for a Boundary Adjustment under the
Administrative Subdivision procedures in Section 26.480.050(c) of the Municipal Code was
submitted and duly processed, resulting in the City-approved and recorded Boundary Adjustment
Plat referenced above. Thus, no application for a Major Subdivision Approval was applicable or
required.
It is also worth noting that Cooper Avenue Victorian Condominium Association, Inc.
caused to be recorded a First Amended Condominium Map on December 13, 2011 in Plat Book
98 at Page 93 under Reception No. 585047 (also administratively approved by the City of
Aspen) which expressly recognized the Strip of Land as being excluded from the Cooper Avenue
Victorian Condominiums General Common Elements, noting the 2006 quit claim conveyances
of the Strip of Land described above.
Any time period for challenging the processing and approval of the Boundary Adjustment
Plat has long passed and the Cooper Avenue Victorian Condominium Association and the
individual unit owners therein have absolutely no claim or interest in the Strip of Land, and they
have no basis for challenging the composition or description of the Subject Property as set forth
in the Boundary Adjustment Plat. Accordingly, we view the neighbor’s objections to the
inclusion of this westerly portion of the Subject Property with the pending HPC application to be
unsupported and wholly without merit.
Please contact the undersigned if you have any questions or desire additional information.
Sincerely,
Thomas J. Todd

RE: 1020 E Cooper Street-Conceptual Engineering Report
Sopris Engineering, LLC Job No. 30111.02
Dear Sara,
Sopris Engineering, LLC (SE) has prepared this letter to summarize the Civil Engineering requirements and
recommendations in support of the potential redevelopment of 1020 E. Cooper Street located in Aspen, CO.
It is our understanding that the project is seeking approval from HPC in support of an affordable housing project on
the subject property. This letter is specific to utility extensions, conceptual site grading and stormwater mitigation
options for the project team to further evaluate as the design progresses towards Building Permit Application.
Conceptual Grading & Drainage, Utility and Drainage Mitigation Plans have been provided as an attachment for
illustrative support of this document.
Background & Existing Conditions
The subject property is located at 1020 E. Cooper Street in Aspen, CO (Parcel ID#273718232006) and according to
Pitkin County Assessor’s webpage the existing building was constructed in 1888 with an effective year built of 1964
and was originally constructed as a single family residence.
Based on our review of the existing conditions survey and site visits the property consists of an existing single story
wood frame house with a building footprint at ground elevation of approximately 1,100 sf. Existing ground cover
includes various concrete walkways and intermittent lawn area/vegetation. Two detached shed structures front the
alley to the north. The total existing onsite impervious area has been estimated at 1,945+/- sf which includes the
existing residence, out structures and concrete pathways. Surface grades and existing drainage patterns generally
slope from the southeast to the northwest across the site with relatively flat landscape grades around the residence.
Existing gutters and a downspout appear to discharge directly to the adjacent ground. As such, tributary roof
drainage appears to be conveyed over the existing ground towards the alley north of the subject property. No other
onsite stormwater improvements were observed during our site visit or indicated on the existing conditions survey.
It should be noted that the site does lies slightly below E. Cooper Street. The design of the improvements
considered raising the sidewalk to coincide with the top back of curb but since this approach would require
improvements on the neighboring property to the east it was not pursued. Instead, offsite basins associated E.
Cooper Street were evaluated to determine whether there were any drainage concerns given this existing condition.
Our findings related to this are further discussed below within the Existing Offsite Basins section.
According to Figure 3.1 of the City’s Urban Runoff Management Plan (URMP) the underlying soils likely consist of
Type B Soils which have moderate infiltration rates. This will be confirmed once geotechnical exploration work has
been performed. The subject property falls within Zone X as identified on FEMA Flood Insurance Rate Map Panel
#08097C0366E, effective date August 15, 2019. Zone X includes areas determined to be outside the 500-year flood
plain.

S OPRIS E NGINEERIN G • LLC civil consultants
The subject property falls within Drainage System 1, Basin 12 as described within the City’s Surface Drainage
Master Plan (SDMP), dated November 2001 prepared by WRC Engineering, Inc. Drainage System 1 currently
consists of street curb and gutter, roadside ditches and a network of storm sewer pipes. According to the SDMP
there is an existing 18” HDPE storm sewer beneath E. Cooper Street, directly south of the subject property.
Preliminary investigation of this existing storm sewer collection system revealed the shallow depths prohibitive for
direct connection of the development’s anticipated stormwater mitigation infrastructure.
An existing electric and communications utility easement (Rec. # 659373) is located at the northeast corner of the
property and accommodates portions of an existing 4’x4’ transformer vault as well as the COA Electric clearance
requirements. Further discussion of the existing easement as it relates to this and future development can be found
in the Site Utilities section of this letter. There is also a 2’x8’ electric easement at the northwest corner of the site
that accommodates an existing transformer located on the neighboring property.
Lastly, according to Figure 7.1a of the City’s URMP the subject property falls outside Aspen Mountain’s mudflow
zone, however it should be noted that the City is in the process of updating mudflow studies and regulations which
may influence any potential mudflow requirements for the subject property.
Existing Offsite Basins
As mentioned above the subject property lies slightly below the flowline elevation of E. Cooper Street and therefore
corresponding offsite drainage basins were evaluated to assess the risk of offsite stormwater runoff entering the
subject property. Based on site visits and our review of the City’s SDMP, Basin 12 was subdivided into several sub-
basins to estimate peak runoff rates and corresponding conveyance capacities. These drainage basins are further
described below and supporting calculations are provided as an attachment to this letter.
Basin OS-1 is an existing basin within E. Cooper Street directly south and east of the subject property. An
existing at grade access to the Chateau Eu Claire and the associated northern edge of the E Cooper Street
attached site walk serves as the northern boundary for the basin. An existing low point and associated inlet was
observed just west of the E Cooper Street bridge crossing of the Roaring Fork River. As such, the eastern limits
of the basin were established by the breakline tributary to this inlet. The southern extent of the basin was
established at the crown of E Cooper Street. Overall imperviousness is estimated to be 100% based on existing
ground cover.
Runoff generated within the basin is collected within a 4’ concrete drain pan directly south of the Riverside
Townhomes. Surface runoff collected within this drain pan continues west within the concrete flowline into a
formal curb and gutter system in front of the subject property (Basin OS-2). The drain pan was field measured to
have an approximate 0.2’ available flow depth and approximately 1.5% longitudinal slope. Based on this
information, runoff generated from a 100 year storm event is estimated to be fully contained within the drain pan
at an approximate 0.14’ flow depth. This analysis concludes that no existing offsite runoff will be tributary to the
site from the north side of the E. Cooper Street right of way east of the subject property.
Basin OS-2 is an existing basin within E. Cooper Street directly south of the subject property. The northern limit
of the basin was established to be the top of curb on the north side of E. Copper Street. The basin is bound by
Basin OS-1 to the east and the projected subject property line to the west. The southern extent of the basin was
established at the crown of E. Cooper Street. Overall imperviousness is estimated to be 100% based on existing
ground cover.

Runoff generated within the basin is collected within an existing curb and gutter system on the north side of E.
Cooper Street. Surface runoff then continues west within the gutter flowline to a curb inlet west of the subject
property, near the intersection with S. Cleveland Street. Portions of the existing curb will be replaced with COA
compliant curb & gutter with this project, however the existing curb height was measured for conservative
analysis. The curb height was field measured to have an approximate 4.5” height, 2” gutter drop and average
1.5% longitudinal slope. Based on this information, the 100 year storm event is estimated to be fully contained
within existing parking lane at an approximate 0.13’ flow depth. This analysis concludes that runoff from the
basin will not overtop the curb and no existing offsite runoff will be tributary to the site from the north side of E.
Cooper Street in front of the subject property.
Basin OS-3 is an existing basin within E. Cooper Street detached sidewalk directly south of the subject property.
The northern limit of the basin was established to be the northern edge of the sidewalk adjacent to the
development. The basin is bound by Basin OS-1 to the east and the projected subject property line to the west.
The southern extent of the basin was established at top back of curb on the north side of E Cooper Street. A
small portion of existing sidewalk from the adjacent Riverside Condo property to the east was additionally
included within the basin limits. Overall imperviousness is estimated to be 75% based on existing ground cover.
Runoff generated within this small basin runs along the southern edge of sidewalk towards the west and likely
evaporates and/or percolates into the adjacent landscape area. Drainage conveyance calculations indicate that
this existing conveyance has adequate capacity and the runoff from this small basin does not enter the subject
property.
Basin OS-4 is an existing basin comprised of the various properties south of E. Cooper Street that contribute
surface runoff to the south side of E. Cooper Street in front of the subject property. This basin was evaluated to
determine whether or not tributary flows would overtop the crown of the road. Overall imperviousness is
estimated to be 85% based on existing ground cover. In addition, a conservative 5-minute time of concentration
was used to estimate peak runoff rates for this larger basin.
Runoff generated within this basin is ultimately collected within the existing curb and gutter system on the south
side of E. Cooper Street. Surface runoff then continues west within the gutter flowline to a curb inlet west of the
subject property. The existing curb height was field measured to have an approximate 5.5” height, 2” gutter drop
and 1.5% longitudinal slope. Based on this information, the 100 year storm event is estimated to be fully
contained within the existing parking lane at an approximate 0.41’ flow depth. This analysis concludes that runoff
from the basin will not overtop the crown of E. Cooper Street and no existing offsite runoff will be tributary to the
site from the south side of E Cooper Street.
To conclude, based on the offsite drainage analysis associated with E. Cooper Street, it has been determined
that offsite flows do not adversely impact the subject property and that the existing condition is found to be
acceptable for redevelopment. Estimated offsite peak runoff rates are summarized within Table 1. In addition,
supporting calculations and a drainage basin delineation plan are included as attachments to this letter.

Proposed Development, Stormwater Requirements and Stormwater Mitigation
It is our understanding that the project will include a remodel and relocation of the existing residence and an
expansion to accommodate multiple affordable housing units. Additional improvements include off-alley parking
along the north side of the property, various walkways, bicycle racks, trash enclosure, landscaping, stormwater
mitigation infrastructure and utility service extensions.
Based on the proposed improvements the project will be classified as a “Major Project” as identified within the City’s
URMP. Based on the location of the subject property the stormwater mitigation requirements will include water
quality treatment for all exposed impervious areas. Onsite stormwater detention is not required for the proposed
improvements as conveyance to the City’s street gutter system will be provided via an improved alley way. Surface
runoff will then sheet flow west down the gravel alley consistent with the analysis provided in the City’s SDMP
prepared by WRC Engineering.
Water Quality Treatment: Based on the estimated total impervious area, the resulting required water quality
treatment volume will be approximately 59 cf. Preliminary investigation for integrating permeable pavers, green roofs
and/or bioretention basins has proven challenging given the nature of the affordable housing development. The
gable type roofs and historic nature of the project prevents utilizing green roofs and the density of the site would
place permeable pavers and bioretention gardens very close to the proposed structures which will require
impermeable liners and underdrain piping that come at an additional cost and these underdrains would end up in the
dry well regardless given the inability to connect directly to the City’s storm drain system. Based on these constraints
a dry well is being proposed for water quality treatment. Dry Wells are a stormwater mitigation BMP that
incorporates manhole structures with perforated barrels at the deeper depths. Washed screened rock is installed
around the exterior of the perforated sections. When sub-soils are capable of moderate to high infiltration rates, dry
wells are considered to be a viable BMP. They dramatically reduce the increased runoff and volume of stormwater
generated from surrounding impervious areas and promote infiltration; thereby improving the water quality of
stormwater runoff.
The required water quality capture volume for a dry well shall be 150% of the design water quality capture volume as
outlined within Chapter 8 of the City’s URMP. Per the City’s URMP dry wells shall not be located within 10-ft of any
structure or 10-ft from a private property line. Based on these criteria there is only one potential location for a dry
well as illustrated on the attached conceptual civil drawings; unless a variance request is pursued. The resulting
anticipated water quality capture volume based on the anticipated proposed impervious areas and a 1.5 factor of
safety is estimated to be 89 cf. Given the minimum depths required to meet Section 8.5.4.2 of the City’s URMP
there will be an additional 60 cf of capacity within the dry well which will provide additional detention and attenuation
of stormwater runoff. Conceptual civil plans are included as an attachment for illustrative support of the proposed
site plan and stormwater mitigation design.
Site Utilities
Coordination with the various utility providers has taken place to verify layouts, routing, and feasibility of serving the
proposed improvements. This section describes our findings. Preliminary utility plans have been included within the
attached civil drawings for illustrative support. Additional details and finalized design will be submitted when a
Building Permit Application is pursued.
Water Service & Fire Flow Analysis
The City of Aspen Water Department is the provider of potable water for the subject property. Currently the site is
served off the existing 14 inch DIP main that runs down E. Cooper Avenue. The existing service size is unknown but

the service is to be capped and abandoned if determined to be inadequate to support the proposed improvements.
A new service tap meeting the fire and domestic demands will be provided per COA Water Department Standards.
The water service is anticipated to be routed to a water entry room near the southeast corner of the historic landmark
building, beneath a proposed porch. The master meter will be located within a tempered space and entrance will be
provided through an access hatch integrated within the porch in compliance with Section 5.8 of the Water
Distribution Standards. A common service line agreement may be pursued by the development to facilitate separate
service feeds to the various units. This will be determined in support of a future building permit application if
necessary.
Final size of the service line will be coordinated with the Water Department staff based on anticipated building
program demands and fire sprinkler suppression requirements. Final fixture counts and resulting consumptive
demands will be determined by the Mechanical Engineer and coordinated with City staff prior to pursuing a Building
Permit Application.
Sanitary Sewer
Aspen Consolidated Sanitation District (ACSD) is the supplier of sanitary sewer service to the subject property and
surrounding area. An existing 8” collector line exists in the alley to the north of the proposed building. There is an
existing service from this line to the existing residence. A shared sewer service will likely be provided for the
proposed development and a new tap and service line is anticipated. The final size of the service line will be
determined by the project MEP in support of building permit design. A small ejector vault and pump system will be
required in order to lift below grade spaces up to the District’s system within the alley. The ejector system is
anticipated to be located exterior of the structure(s) and located on the north side of the development. The design of
the system will be provided in support of any future building permit application.
Shallow Utilities
The shallow utilities proposed to serve 1020 E. Cooper Avenue include electric, cable, and telephone. An existing
gas main does run along the alley however natural gas service is not being proposed at this time. The information
provided within this section includes utility locates obtained during the improvement survey as well as discussions
with the individual utility providers.
City of Aspen Electric currently serves the subject property via a transformer located within an existing dedicated
easement (Rec. # 659373) near the northeast corner of the subject property. The existing transformer and vault
is primarily located on the adjacent property to the east, however a small portion of the transformer and vault lie
within the City’s Right of Way. The size and location of the existing transformer was discussed and coordinated
with City Engineering Staff. Relocating the existing transformer would require an additional splice vault within
the alley. City Staff decided additional infrastructure was not desirable and determined a new 4-ft diameter vault
is to be centered beneath the existing transformer. A new 5’x5’ transformer lid and upgraded transformer will be
placed atop the vault and portions of the upgraded infrastructure will remain within the alley. However, City
Engineering did request an easement on the subject property be provided to accommodate shifting the
transformer to the south and out of the right-of-way should the City pursue this in the future. After further review
of this option it has been determined that the existing onsite electric easement at the northeast corner is
adequate to comply with the separation requirements if/when the transformer is ever moved further to the south.
Comcast Cable service is currently provided via a pedestal located within an existing easement on the property
directly adjacent to the west. The upgraded service is proposed to come from this same pedestal and will follow

a similar alignment to the existing line. Cable service is anticipated to be routed below grade directly to the north
building and routed internal to the building to serve the various units.
Century Link service is currently provided via an existing pedestal located near the northwest corner of the
property. New service to meet the development’s needs is anticipated to originate from this existing pedestal.
A Conceptual Utility Plan has been included as an attachment (C-2.0) for illustrative support. A final Utility Plan will
be submitted in support of any future building permit.
Conclusion
Based on our evaluation of the existing site conditions and proposed development the project has a viable option for
providing water quality mitigation that complies with City standards and offsite drainage basins will not have any
adverse impacts to the proposed development. In addition, utilities necessary to serve the project are available.
The design of all onsite stormwater mitigation infrastructure, water quality treatment facilities, and utility service
extensions, to include size and location, will be further analyzed as the project design progresses. Final designs will
be provided with any future building permit application.

Response to DRC Review Comments
Building Department
Comment 1: Will be addressed at building permit.
Comment 2: The egress well has been removed from the revised plan.
Comment 3: Will be addressed at building permit.
Comment 4: Unit 103 has been redesigned to be Type B accessible unit.
Comment 5: The clear dimensions of the column work with the door/ramp access of a typical minivan.
Comment 6: Trash is on accessible route as confirmed by Building Department. Clearances will be
included in building permit.
Comments 7 – 14: Will be addressed at building permit.
Engineering Department
I reviewed the conceptual drainage report Jesse sent over last week and it addresses all of my comments
for DRC. I spoke to the Electric Department and it is acceptable to have the 2’x8’ easement in the proposed
parking space since it is to the side and not in front of the doors.
A few things to note for building permit submittal
1. Fire flow calcs will be required if a 4” service line is needed. Calcs that show a 2” service line
fails will also need to be provided.
2. The conceptual drainage report calls out that the alley will be re-designed to accommodate flows
to the curb and gutter, this design will need to be included with capacity calculations.
3. The transformer to the east has an existing easement that according to the conceptual drainage
report, is adequately sized for a future relocation. Show the dimensions of the easement (on 1020
E Cooper and the neighboring property) on the utility plan to confirm the easement meets COA
Electric standards for transformer easements. If the dimensions do not comply with COA
standards, the easement will need to be adjusted during building permit review.
Response – these items will be included in the building permit application. An electric easement drawing
demonstrating the proposed location for the upgraded vault/transformer was submitted to the City of Aspen
Engineering Department on December 21, 2020 for review.

RE: Application of 1020 E. Cooper, LLC
Multi-Family Affordable Housing at 1020 E. Cooper Ave.
Dear Commissioners:
This firm represents the Riverside Condominium Association (“Riverside”) and the
Cooper Avenue Victorian Condominium Association, Inc. (“Cooper Victorian”) (Riverside and
Cooper Victorian are referred to collectively herein as the “Associations”). These complexes are
located on either side of 1020 E. Cooper Avenue, Aspen, Colorado at 1024 E. Cooper Avenue
and 1012 E. Cooper Avenue, respectively. This letter will serve as the Associations’ concerns
and opposition to the application submitted by 1020 E. Cooper, LLC (“Applicant”) for approval
of a multi-family complex (the “Application”) that is scheduled for public hearing before you on
January 13, 2021.
As you are aware, members of these two Associations actively participated in the review
process for the 2019 proposal by Applicant to redevelop this property with the relocation of the
historic landmark and an addition thereto to create a larger single family home. At that time,
members of Riverside and Cooper Victorian opposed the project due mainly to the proposed
mass and scale of the addition, concerns that were shared and voiced by HPC members, who
narrowly approved the project on a vote of 4-2. The 2019 proposal was called up by the City
Council and then remanded back to HPC due to these same concerns of mass and scale pursuant
to Sections 10.3 and 10.4 of the Historic Preservation Guidelines. The 2019 proposal was never
finally approved.
Specifically, HPC and City Council members were concerned with the large addition on
the back of the historic home and the effect on the neighbors. When the HPC considered the
proposal at its August 26, 2020, meeting, it came to light that the applicant’s re-design had raised
the roof another few feet, without discussion with HPC, and several Commissioners still believed
Exhibit C- Public Comments Received
155
that the mass and scale of the project was not appropriate. The hearing was continued to
September 23, 2020, but it appears that the Applicant, in accordance with a prior e-mail to
concerned neighbors, decided to revise the project to its current form – an application for a
multi-family development.
As this current application is for a new building in addition to the relocation and remodel
of the historic home, Section 11 of the Guidelines applies rather than Section 10. Regardless, the
concerns regarding mass and scale still exist, and additional concerns regarding parking and
subdivision are also raised with this new proposal. Specifically, Section 11.2 states that the new
building should not overwhelm the historic structure; Section 11.3 states that the new building
must be similar in scale and proportion to the historic structure; and Section 11.4 states that the
primary plane of the front of the new building should not appear taller than the historic structure.
Moreover, since this is a multi-family complex, the provisions of the Americans with Disabilities
Act (“ADA”) apply, pursuant to Section 12.1.
The Application states that the existing historic structure will be relocated toward the
front of the lot and will be converted into two two-bedroom units, with a new structure located
behind it that will consist of three units – a two-bedroom and two three-bedroom units. The
Application states that these units will be sold to local employers to utilize as affordable housing
pursuant to either Category 3 or 4 of the APCHA guidelines, and that Applicant expects the
project to house 12.75 full time employees. It is worth noting that all of the renderings of the
project show families living in these units, meaning that this maximum provision of employee
housing likely will not be realized.
The Application states that the new building will nearly reach the allowed maximum
height of 32 feet, which is approximately 3 feet higher than the 2019 proposal, and over double
the height of the existing historic structure. Renderings of the project in the Application show a
deck on the front of the new building that is even above the roof of the historic structure.
Although the Application states that by setting this building back from the historic structure the
“perception of the height difference” is reduced, it is difficult to see how one can reduce a
doubling of height. Furthermore, the 2019 proposal, at staff’s request, demolished the non-
historic addition to the landmark home as an aid in reducing the mass of the project. The current
proposal appears to maintain this non-historic addition in order to allow for more square footage
for units in the landmark. Clearly, the mass and scale of the proposal has not been reduced from
that in 2019 and, in fact, is increased as described herein and by the creation of five units on the
property, taking the mass and scale consideration from that of a single family to potentially
seventeen occupants if each unit is occupied by a family.
Applicant wants HPC to consider the fact that the Riverside Condos and the Cooper
Avenue Victorian Condos are “three stories” and thus that should make this project acceptable in
mass and scale; however, this ignores the directive of the Guidelines, which requires HPC to
consider mass and scale as compared with the historic structure. How the project appears in
mass and scale to neighboring properties is irrelevant, especially when these neighboring
structures are not historic landmarks. The criteria of Sections 11.3 and 11.4 of the Guidelines
Exhibit C- Public Comments Received
156
simply cannot be met. Especially in light of the fact the 2019 project, which was of a smaller
mass and scale of this proposal and for which HPC and City Council had concerns that similar
Sections 10.3 and 10.4 (applying to additions to historic structures) could not be met, a finding
that the mass and scale of this proposal is appropriate would be arbitrary and capricious and
could subject the City to costly and protracted litigation.
It is important to note that the cover letter for the Application states, at the top of page 4,
that “[t]he units are proposed to be rentals that are sold to Pitkin County employers to rent to
APCHA qualified employees. . .” Yet, the Application specifically states that a historic lot split,
pursuant to Section 11.5 of the Guidelines, is not being requested. As the City Attorney knows, it
is unlawful to sell units separately unless a subdivision or condominiumization has been
approved. Our review of the relevant public records and other available materials indicates that
no subdivision agreement has been approved for this property. That critical issue needs to be
addressed by the Applicant in order for this project to qualify as affordable housing and is
relevant to the issue of parking for this proposal. Absent proper land use approvals that are a
prerequisite for the proposed development, HPC would be unlawfully exceeding its jurisdiction
and abusing its discretion in approving the Application.
Pursuant to Section 26.515.040 of the Aspen Municipal Code (“City Code”) and Table
26.515-1 therein, Applicant is to provide one parking space per unit, which means five parking
spaces. Applicant proposes four parking spaces, one of which will have to be designated and
designed as an ADA space (which is required by Section 12.1 of the Guidelines), with a payment
of cash-in-lieu to satisfy the fifth space requirement. In support of the proposition that this will
be sufficient parking, the Application states that car share and We-Cycle memberships will be
offered to tenants along with a “welcome packet with alternative forms of transportation, bike
and walking trail maps, and bus schedules” in order to discourage car ownership. However, if
these units are to be sold to various employers, as the Application contemplates and as discussed
above, Applicant has no control over whether these proposals will be followed. Furthermore, it is
unrealistic to believe that twelve or more people occupying the units will, collectively, only own
three cars (the ADA parking space will not be available for use unless a resident holds an ADA
parking permit). Although the letter of the City Code may be technically met by this proposal,
HPC is duty-bound to consider, in a practical sense, this impact on the historic property that has
always been a small, single-family home necessitating only one or at most two on-street parking
spots. If approved, the five units could easily end up needing twelve parking spots (one per
bedroom), creating a major problem for the surrounding neighborhood and congesting an
already-busy dense part of town – not to mention diminishing the charm of the historic property
at issue. Even local employees have many reasons to have to run errands in town or to leave
Aspen to meet basic shopping or travel needs for which a car is necessary.
Section 12.1 of the Guidelines requires that this project comply with the ADA. The
Application provides for one ADA parking spot but otherwise does not mention (much less
prove) compliance with ADA accessibility requirements. Every unit is either more than one story
or only accessible by stairs. It is unclear whether common areas would even be ADA-compliant
Exhibit C- Public Comments Received
157
or -accessible. In fact, the Application fails to address Section 12.1 at all. For this reason alone,
the Application must be denied for failure to satisfy Section 12.1’s criteria.
As discussed throughout the Application, the subject property is located in the
Residential Multi-Family (“RMF”) Zone District, which is governed by Section 26.710.090 of
the City Code. As City staff members know, and the Commissioners too, Section 26.710.090(d)
requires lots to have a minimum of 6,000 square foot area and a minimum width of 60 feet. The
subject lot is 4,379 square feet. There is an exception in Chapter 26.312 of the City Code,
entitled “Nonconformities,” that provides an exception that “a lot of record containing a property
listed on the Aspen Inventory of Historic Landmark Sites and Structures need not meet the
minimum lot area requirement of its zone district for historic structures.” See Section
26.312.050(c). However, unlike the provision in the section immediately prior to this, which
states that certain lots created before 1971 that “do not meet the requirements for lot width and
area” can continue as nonconforming (see Section 26.312.050(b)), the historic landmark
nonconforming lot must nonetheless meet the zone district lot width requirements. In this
instance, such cannot be met, as the lot is less than 60 feet wide. Furthermore, the purpose of the
Nonconformities Chapter is “to permit nonconformities to continue, but not to allow
nonconformities to be enlarged or expanded. The provisions of this Chapter are designed to
curtail substantial investment in nonconformities in order to preserve the integrity of the zone
districts and the other provisions of this Title but should not be construed as an abatement
provision.” The City Code dictates that nonconforming historic landmark sites must meet all
provisions of Chapter 26.415 concerning Historic Preservation. As set forth above, the mass and
scale of the proposed project do not meet the Guidelines’ requirements. That indisputable fact,
coupled with the small size of the subject lot (enhancing even more the inappropriate mass and
scale of the subject project), certainly enlarges and expands the existing nonconformity in
violation of Chapter 26.312 of the City Code. For these additional reasons the project should be
denied. If HPC fails to require compliance with that City Code requirement, it will be exposing
the City to legal challenge.
Finally, with the small lot size and the additional strip of land that was added to it from
the lot of 1012 E. Cooper pursuant to the 2006 adverse possession claim (see Letter from Tom
Todd to HPC dated 10/30/20 included in the Application), the proposed new building would sit
only seven feet from the Cooper Avenue Victorian building since that is barely two feet from the
adjusted lot line and the proposal is up to the five-foot sideyard setback. The fire department
requires a minimum ten-foot distance between multi-family buildings. This is yet another
example of the project’s inappropriate mass and scale, and another reason that approval of the
Application is inappropriate and contrary to the applicable criteria.
In sum, we respectfully request that HPC take a hard look at the mass and scale of this
proposal and the criteria of Sections 11.3 and 11.4 of the Guidelines, in conjunction with the
review and discussion of the prior proposal for this property in 2019 and 2020 and concerns
therewith, along with the City Code’s Nonconformities Chapter and safety requirements . HPC
should not be persuaded or sidetracked by the proposal to bring addition affordable housing units
Exhibit C- Public Comments Received
158
to the center of Aspen – this is not the place for such a proposal, not only because it dwarfs the
historic structure and ignores the realities of car ownership and the occupation of units, but also
because it enlarges and expands a nonconformity and creates a fire hazard. Furthermore, HPC
must consider the requirements of Section 12.1 of the Guidelines, which are not even discussed
or addressed by the Application.
For these reasons, HPC should vote not to approve the Application.
While the Application is laudable in some respects, this is simply the wrong location in
Aspen for the proposed development. We are confident that HPC and City staff will come to the
proper conclusion that the Application is neither viable pursuant to the Guidelines nor legally
permissible.
Please do not hesitate to contact me with any questions regarding the Associations’
concerns.
Very truly yours,

Dear Members of the Historic Preservation Commission,
As a resident of Aspen for over fifty years, I have long admired the emphasis Aspen has put on
maintaining the unique history of our community. The is evident in the role your commission
has played in protecting our historic properties.
I live directly to the East of 1020 Cooper and my home is on the lower level of the 1024 Cooper
complex. My property is my retirement and I’m very afraid of what I have seen with the plans
for 1020 Cooper the last couple of years. It’s a repetitive cycle – someone buys the property,
puts together plans to maximize their profits, and then tries to bend / break the HPC rules to
suit their needs. Why do people continue to buy this property if they don’t want to build within
the HPC guidelines? They are very aware of the HPC guidelines before they elect to purchase
the property.
This project is even larger and more massive than the last one that was rejected by the City
Council and the HPC. If this project were approved, I would have no sunlight into my unit and
my view out of my windows would be a blank wall. My home’s value would drop dramatically.
Our alley is unpaved and already overwhelmed with cars. How would this many people only
need 3-4 parking spots?
The HPC guidelines were put in place for a reason – to prevent huge, monolithic structures like
this from being built. I have faith the commission will do the right thing and not approve this
project that will line the pockets of its developers with profits while watching the property
values of neighbors deteriorate.
This is a wonderful, historic property that just needs the right buyer.
Godspeed,
Len Horowitz

To whom it may concern,
RE: 1020 East Cooper Ave---redevelopment.
I am absolutely not opposed to the employee housing that is proposed.
I live next to 949 East Cooper Ave (over 30 years)- The St Regis Hotel employee housing;
and also with in ear shot of The Ski company’s housing on the corner of East Cooper and
South West End.
I do have problems with a few points:
1- Mass and scale; the plans I have seen so far ; it portends a big boxy oversized structure-not
in character with the changing neighborhood
2- The parking is totally inadequate for volume of tenants suggested.
In fact with the present units on East Cooper, parking is full all summer and winter on both
sides of East Cooper; from City Market to the roaring fork bridge---off season is getting
increasingly busier too.
3-The present designs are totally misrepresented on the back alley size of their plans—it
is a narrow alley
4-Their car count for alley parking is totally out of line with reality.
–A few suggestions as this project goes thru review_
-on site parking must be increased-reduce bedroom count.
-.
-No side setback variances should be granted
-There should only be 2 entrances one front and one rear of building .
-Minimum 12 month leases or perhaps go from rental to owner occupied to respect serenity of
surrounding neighborhood.. Strict HOA rules to not alow clutter on decks or property
itself, 1024 É Cooper has these rules along with maximum occupants allowed and mandatory
quiet hours
-This is not a location to try over size maximum density.

Happy New Year to all!
Before the meeting scheduled January 13th 2021 I wanted to forward a column written by the
much loved and outspoken, Su Lum. Over and over I have listened to the developers talk of
how Su would be behind this project and we should give this project our blessing?? The
developer obviously didn’t know Su Lum AT ALL or is blatantly trying to mislead everyone!~
Anyone who knew anything at all about Su Lum knew cramming a bunch of condos (employee
or not) on a small lot in the core of Aspen was not what preserving Aspen was or is about and
or what she stood for. She would be rolling in her grave to know a developer took over her
beloved little house and turned it into another oversized condo project to get tax and or other
credit and breaks for an even larger project!
https://www.aspentimes.com/opinion/lum-preserving-the-splinters/
Aspen does not need another property like 1024 East Cooper approved and built with no
consideration for preserving any green space at all. We don’t need more like this on the main
street coming into town! PLEASE don’t allow anyone to take away the front yard of 1020 East
Cooper. Take that and you might as well build a box and cover the entire property, the charm
is gone! They fact that the tiny lot could house 15 individuals plus guest is a huge issue. There
is not near enough parking for the project considering how many people can live there at any
certain time! MOST people in Aspen have a car and/or a motorcycle. I have lived in Aspen
since ’95 and I can honestly say I cannot think of a sole back then or now that didn’t/doesn’t
own a car or motorcycle. (most cars in Aspen area larger SUV’s ) Are applicants going to be
required to sell their vehicles in order to rent? Or does no one care, just cram more down 82
and in the Eastend neighborhood?!?!? Please take these well founded concerned into
consideration.
I respect that your job is hard and want to thank you for doing what you do.

Subject:1020 E. Cooper Project - Please Include in Public Comments for HPC Board Mtg on Jan 13
Date:Thursday, January 7, 2021 4:38:06 PM
Dear Kevin Rayes and Aspen HPC Board,
As a resident of 1012 E. Cooper, I’m writing to you regarding my concerns about the new
1020 E. Cooper project.
As with the prior 1020 E. Cooper development project by David McMahan, my primary
concern is that the current plan for the addition is still both too tall and too large for the lot and
in relation to the historic building. As we have stated all along about both projects, the mass
and height of the new structure are still not compliant with 10.3 and 10.4 of the HPC
Guidelines as they pertain to these issues. Although affordable housing is a worthy pursuit,
HPC’s primary responsibility is to ensure that development projects are compliant with and
are in the spirit of HPC Guidelines. And this new re-development is actually larger than the
previous one, and thus dwarfs the historic house.
I also find it curious that although HPC has strict instructions about the need for the new
addition to look quite dissimilar from the historic structure, in this case, per their latest
rendering, the buildings actually look very similar – both are very basic, angular structures
painted in an extremely dark monochromatic color. Honestly, it sort of looks like Darth
Vader’s house, and not at all like a happy multi-family complex, as it was initially pitched to
the neighbors. It makes one wonder who their target residents really are? And are the
developers being authentic when they say they want to build a structure that fits among their
neighbors and in that neighborhood. I would give it a 2 out of 10 for attractiveness and
appropriateness.
And speaking of neighbors, the 1020 E. Cooper Project’s historic home’s placement on the lot,
within five feet of the sidewalk, is out of alignment with both its own historic placement on
the lot and its neighbors to the west. Two of those neighbors are themselves historic Aspen
homes with traditionally sized front yards and the other is ours at 1012, a replicated Victorian
with a large front yard. We realize that the neighbors to the east are at the sidewalk but those
projects were not historic developments, and were built decades ago anyway.
Lastly, another big concern is the lack of parking that 1020 is going to have. It is simply not at
all realistic to think that the 10+ people that will be residing there will only need four parking
spots. They will need at least 8-10 parking places and possibly more depending on if the lot is
condominiumized (as proposed) and the units are sold to a variety of local business owners to
then rent to their employees. If there are two 3-bedroom units and three 2-bedroom units, there
could be at least three adults in each of the 3-bedroom units and at least 2 adults in each of the
2-bedroom units, which would mean a total of at least 12 adults living in that complex. And
since their APCHA application is for a Category 4 or below rating, then there could be many
more residents than that if it’s designated Category 1 or 2, which often means young single
people who’ll be sharing rooms. Parking will be a huge problem not only for the local
residents who have parking in the back because there is absolutely no extra parking in our
alley, but also for street parking. E. Cooper is almost always completely parked up during
winter, spring break and summer – and often fall too during leaf season. This is precious
parking for local residents, contractors and day-trip visitors, many of whom come over the
Exhibit C- Public Comments Received
163
Pass when it’s open. Basically, there isn’t room for extra dedicated parking spots on the street
without “bumping” others who already park there.
At the end of the day, this narrow, undersized lot with a historic home previously owned by a
popular Aspen newspaper columnist is really best suited for a single-family dwelling or
perhaps a duplex, not a large multi-unit complex. This project in no way honors Su Lum, our
neighbor who we knew, and her love of Aspen, its history, her home and her garden. She must
be turning over in her grave at the idea of this giant black monolith that swallows up almost
her entire lovely lot.
Aspen HPC Board, as you are directed to honor and appreciate Aspen’s heritage and historic
resources, I respectfully request that you seriously consider what I have said and prioritize
Aspen’s history and the neighborhood’s wellbeing over that of a corporate real estate
development team.
Mr. Rayes, I’m planning to attend the meeting virtually but in case I can’t or there is a
technology glitch, please include my email to the board as part of the public comments.
Thank you for your service to Aspen.

Subject:1020 East Cooper Avenue / Stephen and Helene Abelman
Date:Friday, January 8, 2021 11:34:39 AM
Dear Kevin, Amy, City of Aspen and the HPC Board,
Happy New Year to you all. We hope you all are healthy and having a good start to 2021.
We, Stephen and Helene Abelman are owners of two condominium units at 1012 East Cooper
Avenue, Cooper Avenue Victorian ( CAV ), just to the west of the proposed 1020 project. We
have concerns regarding the size and intensity of the project, along with the legal issues
surrounding this project.
The history of this property, with the McMahon Family's previous application proposal for a
single family home, shows both size and mass concerns, not only by the neighboring property
owners, but ALSO by the HPC Board and the City of Aspen. The legal guidelines are again
being ignored in the present 1020 proposal.
We are very much in favor of affordable housing in Aspen, but do not feel the pursuit of
affordable housing has the rights to ignore the present legal and building guidelines relative to
lot size, presently set by the HPC Board and the City of Aspen.
Along with the mass and scale issues, the surrounding parking situation is also, presently
difficult at best. Adding the 5 units, of any type makes parking even more problematic.
Having 5 units, most likely 10+ people living at 1020 East Cooper, will make for a parking
nightmare. as the building can only have 4 parking spaces, 3 regular spaces and 1 ADA
designated space.
Another problem that needs to be addressed is the close proximity of the proposed 1020
structure to both buildings on the east and west sides, thus causing a fire hazard issue if our
fire department needs to get in between the buildings.
In the end, if any of us as individuals, proposed building a structure as large as this proposed
project, we would clearly be denied. This is what occured with the McMahan's, after going to
the HPC and the City of Aspen. It is not right that now, due to corporate developer pressure
on the HPC Board and the City of Aspen, an entire neighborhood has to endure a project
which does not fit legally and physically on this smaller property. It is quite obvious, in
looking at the renderings and the potential number of residents living on this small property ,
that the project size is not appropriate, nor sensible.
A single family home, duplex or 3 unit structure is a much more practicable solution.
Thanks for reading our concerns and please pass them on to the HPC Board, along with the
other public comments regarding this project.
Kind regards,
Stephen and Helene Abelman
