RE: 533 West Hallam Final Design Application
Dear Commission and Ms. Yoon:
Please accept this application for Final Design Review for the project at 533 West Hallam Street. HPC
granted Conceptual approval, the 500 sf FAR Bonus and variations on April 11, 2018 via HPC Resolution
Number 4, Series of 2018. City Council agreed with HPC’s decision and did not exercise their call-up
authority.
The Final Design application details the historic preservation plan to restore the home, proposed materials,
windows, lighting, and other architectural details. The materials shown during Conceptual Review are
unchanged in this proposal. A preliminary storm water management plan is included in the drawing set
as required in the HPC conceptual approval.
We look forward to presenting this final step in the review process for the Duncan’s home. Please let me
know if you need any additional information to complete your review.
Kind Regards,
Kind Regards,

Final Design Review
Exhibit A – Final Design Review
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:
1.1 Preserve original fences.
• Replace only those portions that are deteriorated beyond repair. Replacement elements should
match the existing fence.
1.2 A new replacement fence should use materials that appear similar to that of the original.
• Any fence which is visible from a public right-of-way must be built of wood or wrought iron.
Wire fences also may be considered.
• A wood picket fence is an appropriate replacement in most locations. A simple wire or metal
fence, similar to traditional "wrought iron," also may be considered.
• Chain link is prohibited and solid "stockade" fences are only allowed in side and rear yards.
1.3 A new replacement fence should have a “transparent” quality allowing views into the yard
from the street.
• A fence that defines a front yard is usually low to the ground and "transparent" in nature.
• On residential properties, a fence which is located forward of the front building facade may not
be taller than 42" from natural grade. (For additional information, see the City of Aspen's
"Residential Design Standards".)
• A privacy fence may be used in back yards and along alleys, but not forward of the front facade
of a building.
• Note that using no fencing at all is often the best approach.
Site Design
Exhibit A
Final Design Review
• Contemporary interpretations of traditional fences should be compatible with the historic
context.
1.4 New fence components should be similar in scale with those seen traditionally.
• Fence columns or piers should be proportional to the fence segment.
1.5 A side yard fence which extends between two homes should be set back from the street-
facing facade.
• This setback should be significant enough to provide a sense of open space between homes.
1.6 Replacement or new fencing between side yards and along the alley should be compatible
with the historic context.
• A side yard fence is usually taller than its front yard counterpart. It also is less transparent. A
side yard fence may reach heights taller than front yard fences (up to six feet), but 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.
Response: The proposed site plan includes removing the non-historic fence along Hallam Street and
constructing a new fence along Fifth Street. The proposed painted wood fences are simple in design and
similar to wood fences found on other historic properties in the West End. For the fence facing Fifth Street,
the space between pickets is equal to the width of the picket as shown below. (Sheet HPC3.07) There is no
fence facing Hallam Street. A property line fence of about 5’6” in height is proposed along the shared
property line.
1.9 Maintain the established progression of public-to-private spaces when considering a
rehabilitation project.
Exhibit A
Final Design Review
• This includes a sequence of experiences, beginning with the "public" sidewalk, proceeding along
a "semi-public" walkway, to a "semi-private" porch or entry feature and ending in the "private"
spaces beyond.
• Provide a walkway running perpendicular from the street to the front entry. Meandering
walkways are discouraged, except where it is needed to avoid a tree.
• Use paving materials that are similar to those used historically for the building style. Concrete,
wood or sandstone may be appropriate for certain building styles.
1.10 Preserve historic elements of the yard to provide an appropriate context for historic structures.
• The front yard should be maintained in a traditional manner, with planting material and sod, and
not covered with paving, for example.
1.11 Preserve and maintain mature landscaping on site, particularly landmark trees and shrubs.
• Protect established vegetation during construction to avoid damage. Replacement of damaged,
aged or diseased trees must be approved by the Parks Department.
• If a tree must be removed as part of the addition or alteration, replace it with species of a large
enough scale to have a visual impact in the early years of the project.
1.12 Preserve and maintain historically significant planting designs.
• Retaining historic planting beds, landscape features and walkways is encouraged.
1.13 Revisions or additions to the landscape should be consistent with the historic context of the
site.
• Select plant and tree material according to its mature size, to allow for the long-term impact of
mature growth.
• Reserve the use of exotic plants to small areas for accent.
• Do not cover grassy areas with gravel, rock or paving materials.
1.14 Additions to the landscape that could interfere with historic structures are inappropriate.
• Do not plant climbing ivy or trees too close to a building. New trees should be no closer than the
mature canopy size.
• Do not locate plants or trees in locations that will obscure significant architectural features or
block views to the building.
• It is not appropriate to plant a hedge row that will block views into the yard.
Response: Mature trees are proposed to be retained during construction. A simple lawn and straight
concrete walkway are proposed in the front yard to provide direct access from Hallam Street to the
restored front porch. A secondary concrete paver walkway that is smaller in width than the main entrance
with grass between the pavers is proposed along Fifth Street. Moveable seating and some planters are
proposed in the yard facing Fifth Street in accordance with Zoning allowances. This corner lot does not
have much yard space on the interior of the lot, so the outdoor area faces Fifth Street. This is largely driven
by the dripline protection of the large cottonwood tree. Consistent with plantings associated with the time
period of the historic resource, rose bushes and lilac shrubs are proposed as noted on the landscape plan
(Sheet HPC 2.00).
1.15 Minimize the visual impacts of site lighting.
• Site lighting should be shielded to avoid glare onto adjacent properties. Focus lighting on walks and
entries, rather than up into trees and onto facade planes.
Response: Site lighting is limited to entrance doors around the perimeter of the building. Short pathway
lights are proposed in the patio area facing Fifth Street. Lighting shall meet the City Lighting Code. (Sheet
EL-1.0)
Exhibit A
Final Design Review
2.7 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, 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.
2.8 Do not use synthetic materials as replacements for primary building materials.
• In some instances, substitute materials may be used for replacing architectural details, but doing so
is not encouraged. If it is necessary to use a new material, such as a fiberglass column, the style
and detail should precisely match that of the historic model.
• Primary building materials such as wood siding and brick should not be replaced with synthetic
materials.
• Synthetic materials include: aluminum, vinyl siding and panelized brick.
• EIFS (synthetic stucco) is not an appropriate replacement for real stucco.
Response: The areas of restoration, as shown on the approved demolition plan and determined by Staff
and Monitor in the field, will match historic siding and original material.
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, operation and groupings of windows.
• Repair frames and sashes rather than replacing them, whenever conditions permit.
• Preserve the original glass, when feasible.
3.2 Preserve the position, number and arrangement of historic windows in a building wall.
• Enclosing a historic window opening in a key character-defining facade is inappropriate, as is adding
a new window opening. This is especially important on primary facades where the historic ratio
of solid-to-void is a character-defining feature.
• Greater flexibility in installing new windows may be considered on rear walls.
• Do not reduce an original opening to accommodate a smaller window or door or increase it to
receive a larger window on primary facades.
3.3 Preserve the historic ratio of window openings to solid wall on a facade.
• Significantly increasing the amount of glass on a character-defining facade will negatively affect
the integrity of a structure.
3.4 Match a replacement window to the original in its design.
• If the original is double-hung, then the replacement window should also be double-hung, or at a
minimum, appear to be so. Match the replacement also in the number and position of glass
panes.
• Matching the original design is particularly important on key character-defining facades.
3.5 In a replacement window, use materials that appear similar to the original.
• Using the same material as the original is preferred, especially on character-defining facades.
However, a substitute material may be considered if the appearance of the window components
will match those of the original in dimension, profile and finish.
Materials
Windows
Exhibit A
Final Design Review
3.6 Preserve the size and proportion of a historic window
opening.
• Reducing an original opening to accommodate a smaller
window or increasing it to receive a larger window is
inappropriate.
• Consider reopening and restoring an original window
opening where altered.
3.7 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.
Response: Original windows are retained and new windows in the
landmark will be as close as possible to the historic profile and will
be wood. Please refer to sheet HPC 3.08 for window details on the
historic home.
4.1 Preserve historically significant doors.
• Maintain features important to the character of a historic doorway. These may 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.
• If the secondary entrance is sealed shut, the original entrance on the primary facade must remain
operable.
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.
4.5 When replacing a door, use a design that has an appearance similar to the original door or a
door associated with the style of the house.
• A replica of the original, if evidence exists, is the preferred replacement.
• A historic door from a similar building also may be considered.
• Simple paneled doors were typical.
• Very ornate doors, including stained or leaded glass, are discouraged, unless photographic
evidence can support their use.
Doors
Exhibit A
Final Design Review
Response: An original door remains
on the property at a secondary entry
facing Fifth Street. The original door is
proposed to be replicated on the front
porch in location B. To meet guideline
4.5, a similar front entry door
facing Hallam Street is
proposed that has references to
the original door style, but is a
product of its own time. The
existing shed door is proposed
to remain on the shed.
5.1 Preserve an original porch.
• Replace missing posts and railings when necessary. Match the original proportions and spacing
of balusters when replacing missing ones.
• Unless used historically on the property, wrought iron, especially the "licorice stick" style that
emerged in the 1950s and 1960s, is inappropriate.
• Expanding the size of a historic porch is inappropriate.
5.2 Avoid removing or covering historic materials and details on a porch.
• Removing an original balustrade, for example, is inappropriate.
5.3 Avoid enclosing a historic front porch.
• Keeping an open porch is preferred.
• Enclosing a porch with opaque materials that destroy the openness and transparency of the
porch is not acceptable.
Porches
Exhibit A
Final Design Review
• Enclosing porches with large areas of glass, thereby preserving the openness of the porch, may
be considered in special circumstances. When this is done, the glass should be placed behind
posts, balusters, and balustrade, so the original character of the porch may still be interpreted.
• The use of plastic curtains as air-locks on porches is discouraged.
• Reopening an enclosed porch is appropriate.
5.4 The use of a porch on a residential building in a single-family context is strongly encouraged.
• This also applies to large, multifamily structures. There should be at least one primary entrance
and should be identified with a porch or entry element.
5.5 If porch replacement is necessary, reconstruct it to match the original in form and detail.
• Use materials that appear similar to the original.
• While matching original materials is preferred, when detailed correctly and painted appropriately,
alternative materials may be considered.
• Where no evidence of the appearance of the historic porch exists, a new porch may be considered
that is similar in character to those found on comparable buildings. Keep the style and form
simple. Also, avoid applying decorative elements that are not known to have been used on the
house or others like it.
• When constructing a new porch, its depth should be in scale with the building.
• The scale of porch columns also should be similar to that of the trimwork.
• The height of the railing and the spacing of balusters should appear similar to those used
historically as well.
Response: The front porches are proposed to be restored to match historic photographs in accordance
with the Guidelines listed above. Sheet HPC 3.10 show a detail of the front porch roof pitch and eave depth.
A window is shown in the 1984 photo provided below, which indicates a window where the current door
is located. The door is proposed to remain since it is unknown whether there was a door or a window in
that location. Floor plans from the 1984 land use case (below) and the 1960s AHS photo (below) guide the
restoration efforts of the front porches.

Exhibit A
Final Design Review
6.1 Preserve significant architectural features.
• Repair only those features that are deteriorated.
• Patch, piece-in, splice, consolidate or otherwise upgrade the existing material, using recognized
preservation methods whenever possible.
• Isolated areas of damage may be stabilized or fixed, using consolidants. Epoxies and resins may be
considered for wood repair and special masonry repair components also may be used.
• Removing a damaged feature when it can be repaired is inappropriate.
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, which traditionally was a
smooth painted finish.
6.4 Repair or replacement of missing or deteriorated features should 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.
• Using overly ornate materials on a building for which there is no documentation is inappropriate.
• It is acceptable to use salvaged materials from other buildings only if they are similar in style and
detailing to other features on the building where they are to be installed.
6.6 Replacement of missing elements may be included in repair activities.
• Replace only those portions that are beyond repair.
• Replacement elements should be based on documented evidence.
• Use the same kind of material as the original when feasible.
• A substitute material may be acceptable if the form and design of the substitute itself conveys the
visual appearance of the original material. For example, a fiberglass cornice may be considered at
the top of a building.
Response: All original architectural details are proposed to remain, unless beyond repair as determined in
the field by staff and monitor. Replacement parts will be based on documentation and will be coordinated
with staff and monitor.
Architectural Details
Exhibit A
Final Design Review
7.1 Preserve the original form of a roof.
• Do not alter the angle of a historic roof. Instead, maintain the perceived line and orientation of the
roof as seen from the street.
• Retain and repair roof detailing.
7.2 Preserve the original eave depth.
• The shadows created by traditional overhangs contribute to one's perception of the building's
historic scale and therefore, these overhangs should be preserved.
7.5 Preserve original chimneys, even if they are made non-functional.
Response: The cross gable roof form was approved during Conceptual Review and is included in the Final
Design application. Eave depth will match the historic portions of the building that remain and precedent
for this type of one story landmark structure in Aspen, subject to staff and monitor review. No chimney is
proposed, as there is no evidence or documentation of where the chimney was originally located.
7.8 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.
• Specialty materials such as tile, slate or concrete should be replaced with a matching material.
7.9 New or replacement roof materials should convey a scale, color and texture similar to those used
traditionally.
• Replacement materials should be similar to those used historically on comparably styled buildings.
• 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.
• If copper flashing is to be used, it should be treated to establish a matte, non-reflective finish.
Response: There are no original roof materials on the existing building – roof materials consist of asphalt
shingles. A cedar shingle roof is proposed for the historic landmark, and the almost flat (and invisible to
the pedestrian) front porch roof is proposed to be a membrane. Original roof rafters are proposed to
remain where possible.
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 primary and roof materials, roof form, windows, doors and architectural details.
• If a secondary structure is not historically significant, then its preservation is optional.
8.2 If an existing secondary structure is beyond repair, then replacing it is encouraged.
• An exact reconstruction of the secondary structure may not be necessary in these cases.
Secondary Structures
Roofs
Materials
Exhibit A
Final Design Review
• The replacement should be compatible with the overall character of the historic primary
structure, while accommodating new uses.
8.3 Avoid attaching a garage or carport to the primary structure.
• Traditionally, a garage was sited as a separate structure at the rear of the lot; this pattern should
be maintained. Any proposal to attach an accessory structure is reviewed on a case-by-case
basis.
8.4 A garage door should be compatible with the character of the historic structure.
• A wood-clad hinged door is preferred on a historic structure.
• If an overhead door is used, the materials should match that of the secondary structure.
• If the existing doors are hinged, they can be adapted with an automatic opener.
8.5 Avoid moving a historic secondary structure from its original location.
• A secondary structure may only be repositioned on its original site to preserve its historic
integrity.
Response: The secondary structure, aka the garden shed, is about 5 x 6 in size and its sits within the side
yard setback. The structure is not shown on the Sanborn Maps, but has been indicated by Planning Staff
to be of historic value to the property. It is approved to be located near the alley and Fifth Street. It will
be stabilized as needed when placed in its new location.
9.5 A new foundation should appear similar in design and materials to the historic foundation.
• On modest structures, a simple foundation is appropriate. Constructing a stone foundation on a
modest miner's cottage is discouraged because it would be out of character.
• Where a stone foundation was used historically, and is to be replaced, the replacement should be
similar in the cut of the stone and design of the mortar joints.
9.6 When rebuilding a foundation, locate the structure at its approximate historic elevation above
grade.
• Raising the building slightly above its original elevation is acceptable. However, lifting it substantially
above the ground level is inappropriate.
• Changing the historic elevation is discouraged, unless it can be demonstrated that it enhances the
resource.
Response: The foundation material will be a concrete scratch coat to match existing. The relationship of
grade to the historic home will be similar to its historic grade. Positive drainage and creating an
interior space that does not have any steps on the ground level result from the minor changes to
existing grade. According to the 1964 photograph, the existing sloping grade is not the historic grade
documented in the photograph.
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 that creates an appearance inconsistent with the historic character of the
primary building is inappropriate.
New Additions
Foundation
Exhibit A
Final Design Review
• An addition that seeks to imply an earlier period than that of the primary building also is
inappropriate.
• An addition that seeks to imply an inaccurate variation of the primary building's historic style
should be avoided.
• An addition that covers historically significant features is inappropriate.
10.4 Design a new addition to be recognized as a product of its own time.
• An addition should be made distinguishable from the historic building, while also remaining
visually compatible with these earlier features.
• A change in setbacks of the addition from the historic building, a subtle change in material or a
differentiation between historic, and more current styles are all techniques that may be
considered to help define a change from old to new construction.
10.11 On a new addition, use exterior materials that are compatible with the historic materials of
the primary building.
• The new materials should be either similar or subordinate to the original materials.
Response: The new addition has similar form and fenestration to the landmark but the architectural
detailing is proposed to be slightly different. The architectural details in the gable ends and the roof
overhangs of the new addition create a subtle distinction between new and old construction that does not
distract from the landmark or confuse the public.
Windows in the addition are all vertically oriented and comprise mostly double hung windows ganged
together to represent a product of its own time and to contrast and to highlight the single double hung
windows in the landmark. Window sashes in the addition are proposed to be metal clad.
The doors in the addition are full light glass doors that contrast the historic doors in the landmark to clearly
represent the addition as a product of its own time.
Restoration of the landmark and the removal of non-historic additions are proposed to enhance the historic
significance of the structure. Exterior materials for the new construction include a narrow horizontal wood
siding as the primary material and a channel lap wood siding and metal panel cladding as a secondary
material on the connecting element and parts of the new addition (Sheet HPC 3.06).
14.3 Keep color schemes simple.
• Using one base color for the building is preferred.
• Using only one or two accent colors is also encouraged, except where precedent exists for using
more than two colors with some architectural styles.
14.4 Coordinating the entire building in one color scheme is usually more successful than working with
a variety of palettes.
• Using the color scheme to establish a sense of overall composition for the building is strongly
encouraged.
14.5 Develop a color scheme for the entire building front that coordinates all the facade elements.
Color – Advisory Only
Exhibit A
Final Design Review
• Choose a base color that will link the entire building face together. For a commercial building, it can
tie signs, ornamentation, awnings and entrances together. On residences, it can function similarly.
It can also help your building relate better to others in the district.
• The complexity of the accent colors should be appropriate to the architectural style of the building.
• Doors may be painted a bright accent color, or they may be left a natural wood finish. Historically,
many of the doors would have simply had a stain applied.
• Window sashes are also an excellent opportunity for accent color.
• Brilliant luminescent or “day-glo” colors are not appropriate.
Response: The proposed color palette is white with dark accents colors. The color scheme is simple and
the same for both the landmark and new addition.
14.6 Exterior lights should be simple in character and similar in color and
intensity to that used traditionally.
• The design of a fixture should be simple in form and detail. Exterior
lighting must be approved by the HPC.
• All exterior light sources should have a low level of luminescence.
14.7 Minimize the visual impacts of site and architectural lighting.
• Unshielded, high intensity light sources and those which direct light
upward will not be permitted.
• Shield lighting associated with service areas, parking lots and parking
structures.
• Timers or activity switches may be required to prevent unnecessary
sources of light by controlling the length of time that exterior lights
are in use late at night.
• Do not wash an entire building facade in light.
• Avoid placing exposed light fixtures in highly visible locations, such as
on the upper walls of buildings.
• Avoid duplicating fixtures. For example, do not use two fixtures that
light the same area.
14.8 Minimize the visual impact of light spill from a building.
• Prevent glare onto adjacent properties by using shielded and focused
light sources that direct light onto the ground. The use of
downlights, with the bulb fully enclosed within the shade, or step
lights which direct light only on to walkways, is strongly
encouraged.
• Lighting shall be carefully located so as not to shine into residential
living space, on or off the property or into public rights-of-way.
Response: Exterior lights and locations are provided on Sheet EL-1.0 in the
drawing set. Simple fixtures are proposed that meet the Lighting Code and
minimize visual impact of light spill from the building. All lights are
downward facing.
Lighting
Exhibit A
Final Design Review
14.17 Design a new driveway in a manner that minimizes its visual impact.
• Plan parking areas and driveways in a manner that utilizes existing curb cuts. New curb cuts are not
permitted.
• If an alley exists, a new driveway must be located off of it.
14.18 Garages should not dominate the street scene.
14.19 Use a paving material that will distinguish the driveway from the street.
• Using a change in material, paving pattern or texture will help to differentiate the driveway from
the street.
• Porous paving materials will also help to absorb potential water runoff typically associated with
impervious surfaces such as asphalt or concrete.
Response: The proposed driveway is very short and accesses a two car garage off of the alleyway. A simple
concrete apron is proposed as the driveway material.

RE: Stormwater Summary for HPC Review of 533 W Hallam
Attachments: Drainage Report for Duncan Skihaus 533 W. Hallam Street, Aspen, CO
SGM is responsible for providing civil engineering services for the redevelopment of 533 W
Hallam including a drainage design to meet City of Aspen requirements as outlined in the City of
Aspen Urban Runoff Management Plan (URMP). 533 W Hallam is also known as “Duncan
Skihaus”. This memo is a supplement to the previously submitted Drainage Report for Duncan
Skihaus, 533 W. Hallam Street, Aspen, CO dated July, 2018.
Water Quality Treatment Features
The two types of features being proposed to treat stormwater runoff for this project are grass
buffers and pervious pavers. These features, or “Best Management Practices” (BMPs), are
discussed in sections 8.5.1.3 and 8.5.1.4, respectively of the URMP. These BMPs were chosen
because of their effectiveness, low maintenance, and inconspicuous appearance.
Grass Buffers
Grass buffers will be used to treat approximately 26% of onsite stormwater runoff. Grass buffers
consist of densely vegetated turf grass that runoff will flow over uniformly. Grass buffers are
effective at trapping sediment from stormwater runoff thus improving the quality of water before
it flows offsite. The grass buffers will be located either outside the pervious pavers or
landscaped areas thus acting as a secondary treatment method for runoff. The buffers will also
slow the flow of runoff and reduce the runoff volume and peak flow through infiltration. Grading
of the landscaped areas and the pervious pavers will be uniform, so runoff is not concentrated
over the buffer. Allowing runoff to flow uniformly over the grass buffer area allows for effective
infiltration and trapping of sediment.
exhibit L
Grass buffers are an aesthetically pleasing stormwater BMP that are easily maintained. Typical
landscaping needs will provide for adequate maintenance of the system with the occasional
removal and replacement of certain areas that have accumulated sediment. Minimal irrigation
will be provided to allow for healthy vegetation coverage without overwatering. With minimal
irrigation the buffer area will not be continuously saturated which will allow for better infiltration
of runoff. Stormwater BMP’s that require more frequent maintenance can often be neglected
and become failing systems. Grass buffers were selected due to the ease of maintenance,
overall effectiveness, and aesthetics that they provide.
Pervious Pavers
Modular Block Pavement (or pervious pavers) will be used to treat the remaining 74% of onsite
stormwater runoff. Pervious pavers are concrete block units with voids that occupy at least 20%
of the surface area. These voids are then filled with sand. Runoff will percolate though the void
spaces and then an additional 3 inches of sand below the pavers which will provide similar
treatment as a sand filter. After percolating through the sand layer, runoff will be enter a 6-inch
gravel layer and will then infiltrate into native soils. An additional benefit of the pervious paver
system is the reduction of stormwater runoff volumes and peak flows through infiltration.
Pervious pavers are advantageous due to their ability for high levels of removal for particulate
pollutants. The addition of the 6-inch gravel base below the sand will act as a reservoir for lager
storms and promote infiltration. Along with the grass buffers, pervious pavers can be
aesthetically pleasing with the wide variety of patterns and colors available.
Runoff from the house will infiltrate through the pervious pavers into the sand filter zone. After
the stormwater is filtered through the sand, it is routed to a gravel layer to promote infiltration as
shown in the schematic drawing below. Some of the pavers are located over the basement
where the thickness of the sand layer has been maximized to promote filtration.
Figure 1: Pervious Paver Profile View
City of Aspen Urban Runoff Management Plan Compliance
The proposed drainage plan for 533 W. Hallam St is designed based on the City of Aspen
URMP requirements. The BMP’s have been slightly oversized to provide for treatment of larger
storms. For more detailed stormwater routing information and calculations, please see the
Drainage Report for Duncan Skihaus, 533 W. Hallam Street, Aspen, CO.

Drainage Report for Major Design 2
1.0 Existing Site
1.1 Description of Existing Site
The physical address of the project is 533 W. Hallam Street, Aspen, Colorado and it is
located on parcel no. 2735-124-32-001. This parcel is approximately 0.14 acres and is
owned by Duncan Skihaus LLC. Current zoning of the property is medium-density
residential (R-6). The existing structures on the parcel are one house and a small shed. The
project focuses on renovating the house while preserving the historic portion of it. The
existing house is 1897 square feet and has two stories with a garage located near the Block
29 alley.
1.2 Description of Existing Drainage
Existing stormwater runs off of several areas of the existing house either as sheet flow or
through gutters and downspouts. On the west and north sides of the site, runoff sheet flows
over grass to the curb and gutter on W. Hallam & 5th St. Runoff on the east side of the
building enters the neighboring property. Stormwater on the south side of the property
enters the alley. No stormwater detention or treatment BMPs have been found on the site.
There is no existing offsite runoff that enters the property. Existing peak flow calculations
have not been provided for this report because detention is not required and runoff will not
cross any other properties before discharging to the City of Aspen (COA) storm sewer
system.
2.0 Proposed Project
The primary purpose of this project is to demolish and rebuild the non-historic portion of the
existing house. Other improvements include the addition of onsite snowmelt and improving
stormwater runoff quality. The proposed project is considered a major project as defined by
the COA Urban Runoff Management Plan (URMP) because more than 1000 square feet will
be disturbed.
The proposed residential development with have a footprint of 3160 square feet. The
historical portion of the property, which has a footprint of 900 square feet, will be moved
north but will remain intact. The main building will be located on the southern portion of the
lot with a footprint of 2260 square feet. The main building’s footprint includes a paved area
that connects the historical portion of the house with the main building. Stormwater quality
improvements will be added through the use of 799 square feet of grass buffer and 1130
square feet of pervious pavers. The grass buffers will be located on the northern and south-
western portion of the lot. The pervious pavers will be located on the western central and
eastern central portions of the lot. No stormwater generated on the site will flow across the
property line on the eastern portion of the lot into the neighboring residential lot. Runoff from
the eastern side of the lot will flow to north through grading and will not be allowed to cross
the property line through the use of a shoring wall that will be exposed slightly above grade.

Drainage Report for Major Design 3
3.0 Proposed Basins
The proposed site has 7 subbasins, as shown in Appendix A. To clearly describe these
subbasins, they have been grouped into 4 basins based on shared discharge locations and
water quality treatment. Stormwater runoff will be routed to designated BMPs for water

Subbasin 1
Subbasin 1 is located in the very north-east corner of the property. Subbasin 1 has a total
and impervious area of 664 and 249 square feet, respectively. This corresponds to 38%
impervious area for the subbasin. This area is mostly a grassed area with the north-eastern
portion of the roof included. Stormwater will be routed from the roof to a grass buffer and
pervious pavers via sheet flow and then north to the curb and gutter on W. Hallam St.
Subbasin 2
Subbasin 2 is located in the very north-west corner of the property. Subbasin 2 has a total
and impervious area of 670 and 232 square feet, respectively. This corresponds to 35%
impervious area for the subbasin. This area is mostly a grassed area with the north-western
portion of the roof included. Stormwater will be routed from the roof to a grass buffer via
sheet flow and then north to the curb and gutter on W. Hallam St.
3.2 Basin B (subbasin 3)
Basin B is located on the north-east side of the site and will collect runoff from the back side
of the roof of the historic house and the north end of the proposed structure. Subbasin 3 is
the only subbasin located in Basin B. Stormwater runoff will flow off the two roof areas over
pervious pavers and then to an additional grass buffer area on the front lawn. This basin is
957 square feet of which 616 square feet is impervious. Pervious pavers and a grass buffer
will be used to treat the remaining WQCV. The proposed pervious pavers are 206 square
feet and the grass buffer is 199 square feet.

subbasin 4.
3.4 Basin D (subbasins 5 & 7)
Basin D is located on the southern half of the site and will collect runoff from the majority of
the proposed house’s roof. Subbasins 5 and 7 are located in Basin D. Stormwater will be
routed from the roof to a grass buffer and pervious pavers mostly located in Subbasin 5 on
the south-west side of the site. Because of the location of subbasin 7, downspouts will be
used to route runoff from subbasin 7 to the pervious pavers. Runoff will then sheet flow to
the curb and gutter on 5th St. This basin is 2148 square feet of which 1254 square feet is
impervious. A grass buffer and pervious pavers will be used to treat the remaining WQCV.
533 W. Hallam Street, Aspen, Colorado June, 2018

Subbasin 5 is located on the west side of the property and extends from the middle of the
property to near the southern most extent of the site. Subbasin 5 has a total and impervious
area of 1314 and 667 square feet, respectively. This corresponds to 51% impervious area
for the subbasin. The roof is on the east side of the subbasin and flow is routed from the roof
to a grass buffer and pervious pavers below.
Subbasin 7
Subbasin 7 is located on the southern portion of the property and extends from the western
most extend to the eastern. Subbasin 7 has a total and impervious area of 834 and 587
square feet, respectively. This corresponds to 70% impervious area for the subbasin. This
subbasin is adjacent to the Block 29 alley to the south and has a garage located on the
eastern side. Runoff generated will not be conveyed through the alley. The runoff from
subbasin 7 will be routed by grading and downspouts and gutters to the pervious pavers and
the grass buffer located in subbasin 5 and the 192 square feet of pervious pavers in
subbasin 7.

4.0 Peak Flow Methodology
Proposed drainage flow rates were determined using the rational method as explained in
section 3.4 of the URMP and rainfall characteristics as explained in section 2 of the URMP.
The rational method calculations can be seen in Appendix C. The following tables list the
parameters that were used and the results determined for proposed conditions.

For the calculation of proposed peak flows, the entire property was modeled as one
subbasin. It was assumed that modeling the site as one subbasin was adequate due to the
small size of the property, and that all runoff generated will be overland flow. It was also
assumed that there would be no channelized flow on the property. There could be
channelized flow on the east side if runoff was routed to this area, but flow will not be routed
to the east. The hydrologic group was determined to be B from Figure 3.1 of the URMP. The
intensity for the 10-year and 100-year storm were determined using Equation 2-1 of the
URMP.
5.0 Water Quality Methodology
The WQCV for the grass buffer and pervious pavers was determined by using the percent
imperviousness and total area for each subbasin. The WQCV calculations can be seen in
Appendix B of this report.
Tree Canopy Credit was calculated as described in section 8.4.1 of the URMP and the
calculations can be seen in Section 3. Runoff from all impervious areas will be treated by
directing the runoff over a grass buffer or pervious paver. Some water from subbasins 1,2,
3, 4, 5, 6, and 7 are treated by directing runoff over a grass buffer that is equal in size to the
impervious area to be treated as directed in section 8.5.1.3 of the URMP. The remaining
runoff from subbasins 1, 3, 4, 5, 6, and 7 are treated by directing runoff over pervious pavers
that are half the surface area of the impervious area to be treated as directed in section
8.5.1.4 of the URMP.

6.0 Maintenance
6.1 Grass Buffer Maintenance
The following maintenance recommendations were found in the Urban Drainage Flood
Control District USDCM: Volume 3 Stormwater Quality (page 6-5 to 6-7) and will be used as
a guide for the maintenance of the proposed grass buffer. Grass buffers should be
inspected at least twice a year for cover and vehicle impacts. Trash and debris should be
removed from the buffer at least twice a year. The buffer should be aerated once a year with
holes of 2 inches in depth and no more than four inches apart. When aerating the buffer,
sprinkler heads and shallow utilities should be marked to ensure they are not damaged. It is
recommended to mow only when weeds need to be removed in the first 3 years. After the
first 3 years the grass should be maintained at 6 inches or more in height. Additional
information on mowing the grass buffer is provided in Figure 1. Irrigation is recommended to
maintain a healthy vegetation cover. In the early summer and fall, irrigation is typically
needed less, but in July and August more irrigation is needed. If native grasses are used,
irrigation should not be needed after establishment but could be useful during long dry
periods. Although irrigation is necessary for the establishment of the grass buffer,
overwatering could cause uneven growth and should be avoided. Every year the irrigation
system should be drained and blownout before the first winter freeze. The irrigation system
should be inspected before reactivation in the spring. Fertilizers and herbicides should be
used only on an as-needed basis and it is recommended to use biodegradable nontoxic
fertilizers and herbicides.

Figure 1: UDFCD Volume 3 - Mowing Recommendations for Grass Buffers
6.2 Pervious Pavers
The following maintenance recommendations were found in the Urban Drainage Flood Control
District USDCM: Volume 3 Stormwater Quality (page 6-15 to 6-17) and will be used as a guide
for the maintenance of the proposed pervious pavers. An inspection of the condition and
observation of infiltration should be completed annually. The pavers will lose infiltration
capabilities over time and it is recommended to use ASTM C1707 Standard Test Method for
Infiltration Rate of In Place Pervious Concrete to measure the infiltration rate of the pavers. A
regenerative air or vacuumed sweeper should be used twice annually and after any significant
site work, like landscaping, is done. However, the timing of vacuum sweeping is variable based
on site conditions and biannual vacuuming may be more often than needed. Sand should never
be applied to the pavers for snow removal as this will decrease the permeability of the pavers.
The proposed pavers will have snowmelt capabilities, but if snow removal is necessary,
mechanical snow removal should be done. If the surface of the paver system ever becomes
completely clogged, remove and replacement of the first ½ to 1 inch of infill. The use of a push
broom is recommended for the replacement of infill.

7.0 Conclusion
It is our conclusion that with installation of the pervious pavers and grass buffer, along with
proper maintenance for these BMPs, the proposed 533 W. Hallam Street project will meet
the criteria outlined in the City of Aspen’s current Urban Runoff Management Plan.

below the base of planned excavation elevation prior to completion of the excavation.
3.6 The micropile walls lateral deflection may be up to about 0.003' per foot of excavation depth at the ROW, and no adverse deflection of the ground surface at
the private property line based on anticipated subsurface conditions.
4.0 Special Provisions
4.1 Wall geometry used in design was based on plans provided by client.
4.2 This design is valid only for B&Y Drilling, Inc. at the subject site. B&Y Drilling shall construct all shoring systems shown herein.
4.3 Excavation shall extend to micropile columns. During the excavation process, material should not be left between the excavation face and the grout/micropile
column.
4.4 The micropile wall designs are valid only for dry surface and subsurface conditions. If surface water or groundwater is encountered during excavation or
installation, RJ Engineering should be notified immediately and the wall may be redesigned at the discretion of RJ Engineering. Surface and subsurface
drainage from adjacent properties should not be discharged at the top or through the micropile wall. Saturated soils may result in materials piping out from
between micropiles resulting in failure and/or excessive wall movements.
4.5 The design life on this micropile wall is 12 weeks. Design life is defined by the beginning of excavation to backfill completion of the foundation wall. If the
duration of the project exceeds the 12 week duration, RJ Engineering shall be contacted to evaluate the performance of the system and determine if the
design life can be extended.
4.6 RJ Engineering is not responsible for maintaining slope stability above and below the micropile wall during construction.
4.7 RJ Engineering is not aware of any utility conflicts. The contractors are responsible for field locating all nearby utilities. Conflicting utilities may require
micropile wall redesign at RJ Engineerings' discretion.
4.8 RJ Engineering is not responsible for quality control, quality assurance, changed conditions or problems resulting from improper construction techniques.
4.9 RJ Engineering is not responsible for construction site safety.
4.10 RJ Engineering is not responsible for wall layout. General contractor or representative of the general contractor is responsible for micropile wall layout.
4.11 Observation of micropile wall installation should be performed by a qualified engineer. Inspection and/or monitoring of the micropile wall after completion of
excavation should be performed. The frequency and duration of the observation and monitoring shall be determined by the qualified engineer. The
qualified engineer shall have experience with design and installation of micropile wall systems using injection bars. Observations shall be made at least on
a weekly basis during installation and during the service life of the system.
5.0 Temporary Ground Nail Wall Materials
5.1 Ground Nails - Grade 75 threadbar or equivalent in accordance with ASTM A615 or Williams injection bar.

f'c=1,500 psi minimum 3 day
f'c=3,000 psi minimum 28 day
5.3 End hardware - Nuts and washers shall be in accordance with ground nail manufacturer's recommendations. Bearing plate shall be in accordance with ASTM A36, Grade 36.
5.4 Shotcrete - Shotcrete mix shall consist of Type II cement in accordance with ASTM C150, potable water and normal weight aggregate in accordance with ASTM C33.
Admixtures, if used, should be non-corrosive to steel.
f'c=4,000 psi (28-day strength)
5.5 Welded wire mesh shall be in accordance with ASTM A185.
5.6 Walers and vertical bearing bars shall be in accordance with ASTM A615.
fy=60,000 psi
5.7 Strip drains consist of 12" wide dimpled cores wrapped in geotextile. The compressive strength of the core should be at least 20 psi when tested in accordance with ASTM
D1621, and it's in-plane flow capacity should be at least 10 gpm/ft when tested in accordance with ASTM D4716
5.8 Centralizers should be plastic that will provide free passage of grout and attached to the nails in accordance with the manufacturer's recommendations. Centralizers not
required for injection bars.
6.0 Temporary Ground Nail Wall Construction Sequence
6.1 Excavate one lift to a maximum depth of five feet.
6.2 Install ground nails at the locations and to the lengths shown on the plans. Ground nail location may vary by up to 6". Tremie the grout from the bottom of the hole up.
6.3 Install strip drains, welded wire mesh, walers and bearing bars as shown on the drawings. Use chairs to hold the welded wire mesh away from the soil as necessary.
6.4 Install shotcrete to the minimum thickness shown on the drawings and to attain the minimum coverages specified herein. Give special attention to filling the void in the
borehole above the grout line. Cold weather protection measures may be necessary.
6.5 Install the ground nail end hardware after the minimum inside coverage specified herein has been attained. While the shotcrete is still wet, embed the plate into the shotcrete
surface until there is no void behind the plate. Handtighten the nut.
6.6 Once the grout and shotcrete have attained 80% of their specific strengths, repeat 2.1-2.5 to the bottom of the wall.
