APPLICANT: John Tricamo REPRESENTATIVE: Jennifer Korge, Ten Over Studio
RECOMMENDATION
Provide a recommendation to the Community
Development Director as to the consistency
of the proposed project with historic
preservation guidelines and architectural
standards for construction in the Railroad
Historic District
1.0 BACKGROUND
The applicant proposes to construct two new
residential buildings: a two-story duplex and
a three-story building with five dwellings, on
a property located within the Railroad Historic
District. A portion of an existing commercial
building will be demolished to accommodate
the duplex building.
2.0 DISCUSSION
2.1 Site and Setting
The property is located on the southwest corner of Islay and Osos Streets, in a Medium
High Density Residential (R-3) Zone and within the Railroad Historic District. The District’s
development corresponded to that of the Southern Pacific Railroad yard, with buildings
constructed to accommodate railway workers, freight and passengers, and employees of
Southern Pacific and related businesses. Surviving historic structures date from 1894 to
1945, the peak activity of the rail yard and the district’s period of significance. The
predominant architectural style is Railroad Vernacular, characterized by simplicity of form
and detailing, favored for its easy construction, and buildings are a mix of simple , yet
elegant houses and practical, industrial-oriented commercial buildings. A description of
the District and its characteristics is provided in the City’s Historic Preservation Program
Guidelines (Excerpt as Attachment A).

Cultural Heritage Committee Report – September 25, 2023
The property is developed with a commercial building, originally two, now joined, dating
from the early 20th Century. It is of a simple rectangular form, clad in vertical wood board
siding, with plain wood window trim and metal awnings. It is a corner building with an
extensive plate glass storefront entry. Following a 1980’s survey of properties within
historic preservation districts, the structure at 1601 Osos was coded as a “Non -
Contributing Property” (a structure that does not contribute to the historic character of the
area) in the listing adopted by the City Council in 1988 (under Resolution 6424), and the
property is not currently included in the City’s Inventory of Historic Resources.
Demolition. As part of this project, a 750 square-foot portion of the existing commercial
building, at the rear of the building, is proposed to be demolished, to provide room for
the new duplex building. As described above, neither the building nor the property have
been determined to be historically or architecturally significant.
2.2 Proposed New Construction
New Construction. Behind the remaining portion of the commercial building at the west
side of the site, a two-story duplex building just under 25 feet tall will be constructed. It
will accommodate two one-bedroom dwellings, each 375 square feet in area. Exterior
material is vertical fiber cement board and batten, accented with a “belly band” between
floors, with rectangular windows, metal awnings, and a flat roof with rounded cornice.
At the east side of the site a new three-story residential building just under 35 feet tall will
be constructed. It will accommodate five new dwellings (three 1 -bedroom units and two
2-bedroom units) each 500 to 560 square feet in area. This building has a rectangular
form with a gently sloping shed roof. Smooth stucco and vertically oriented fiber cement
board are the primary exterior materials. Articulation is provided by reglets within the
stucco walls, a board and batten pattern for the cement board, inset balconies (on the
north elevation) with “wood-look” accent siding, and a regularly spaced pattern of
rectangular windows.

3.0 EVALUATION
Guidance for construction within historic districts is provided in the City’s Historic
Preservation Program Guidelines and the Secretary of the Interior’s Standards for the
Treatment of Historic Properties.1 In addition, the Railroad District Plan includes
architectural guidelines that supplement the City’s existing architectural guidelines, for
new development within the Railroad District. Relevant applicable guidelines, standards,
and recommendations from these documents are outlined below.
3.1 Historic Preservation Program Guidelines
Alterations to Historic Resources
§ 3.2.1 (c)
Architecturally
compatible
development within
Historic Districts
New structures in historic districts shall be designed to be
architecturally compatible with the district’s prevailing historic
character as measured by their consistency with the scale, massing,
rhythm, signature architectural elements, exterior materials, siting
and street yard setbacks of the district's historic structures. New
structures are not required to copy or imitate historic structures, or
seek to create the illusion that a new building is historic..
§ 3.2.2
Architectural
compatibility
The CHC reviews development in historic districts for architectural
compatibility with nearby historic resources, and for consistency with
applicable design and preservation policies, standards, and historic
district descriptions in Section 5.2. New development should not

sharply contrast with, significantly block public views of, or visually
detract from, the historic architectural character of historically
designated structures located adjacent to the property to be
developed, or detract from the prevailing historic architectural
character of the historic district.
Discussion: The proposed new construction is two- and three-stories in height, consistent
with the scale of existing residential and commercial development in the vicinity. Facades
and entries are oriented to the street, in keeping with common site characteristics noted
for the Railroad Historic District in the City’s Historic Preservation Program Guidelines
(Attachment A). The new buildings exhibit simplicity in form and detailing and do not
sharply contrast with the characteristic architectural styles in the District. Although they
depart from traditional residential styles to some extent, they are consistent overall with
the Architectural Guidelines for the Railroad Historic District (discussed below, §3.3) and
do not detract from the District’s prevailing character.
3.2 Secretary of the Interior’s Standards (Rehabilitation)
Standards for Rehabilitation
9: New additions, exterior alterations, or related new construction will not destroy historic
materials, features, and spatial relationships that characterize the property. The new work will
be differentiated from the old and will be compatible with the historic materials, features, size,
scale and proportion, and massing to protect the integrity of the property and its environment.
Setting (District / Neighborhood)
Recommended Not Recommended
Identifying, retaining, and preserving building
and landscape features that are important in
defining the overall historic character of the
setting. Such features can include circulation
systems (roads and streets); furnishings and
fixtures (light posts or benches); vegetation,
gardens and yards; adjacent open space
(fields, parks, commons, or woodlands); and
important views or visual relationships.
Removing or substantially changing those
building and landscape features in the setting
which are important in defining the historic
character so that, as a result, the character is
diminished.
Discussion: The Secretary of Interior’s Standards provide guidance on rehabilitation of
historic buildings, including approaches to work treatments and techniques that are either
consistent (“Recommended”) or inconsistent (“Not Recommended”) with the Standards,
specific to various features of historic buildings and sites. New construction will not
materially alter historical characteristics of the subject property since, as noted above, the
property is not included in the Inventory of Historic Resources.

Cultural Heritage Committee Report – September 25, 2023
3.3 Railroad District Plan (Architectural Guidelines)
The Railroad District Plan includes Architectural
Guidelines for new development within the Railroad
District. Some of the more common architectural
elements exemplifying the Railroad Vernacular
architectural style are illustrated in the Plan, providing a
“menu” of elements that can be incorporated into new
development projects. The style of new buildings is to be
consistent with these guidelines and should complement
the District’s historic character, but new buildings need not include all of the described
elements, nor be designed to be a replica of a historic building. These guidelines are also
provided as an attachment to this report, for reference (Attachment), and the consistency
of elements of the project design with these guidelines is summarized below.
Building Form, Massing, and Roof Lines. Both new buildings employ simple, rectilinear
forms. Massing on the site is concentrated at the ground level, with lesser volume at the
second and third levels of site development. The taller building exhibits a gently sloping
roof form with modest overhang, in contrast to the flat roof forms of the duplex and existing
commercial building. While this form does not replicate the steeper bracketed roof forms
of some commercial and residential Railroad Vernacular buildings it does echo a simpler
and more gently-sloped industrial shed roof form observed elsewhere in the District.
Doors and Windows. Doors and windows for the duplex building largely continue the
simple pattern of the existing commercial building it is situated behind. The larger building
exhibits a more interesting design, with plans showing symmetrical multi-panel door and
window forms, including the balcony doors that dominate the b uilding’s north elevation
(see Fig. 4) and divided lite windows on all sides of the building. Windows here are
essentially vertically oriented, but with the shape of openings closer to square, and are
largely arranged in pairs. Windows within board and batten walls are given fiber cement
trim and those on stucco walls are slightly recessed.

Item 4b
ARCH-0333-2022 (1601 Osos)
Cultural Heritage Committee Report – September 25, 2023
Surface Treatment and Colors (Plaster / Masonry Buildings). As with doors and windows,
the smaller duplex building utilizes a design that echoes the commercial building in front
of it, using vertical board and batten fiber cement that relates closely to the existing
building’s vertical wood board siding. The larger new building picks up this pattern on its
east side, transitioning to smooth stucco wall surfaces on its western half. Although stucco
is used, it is smooth in texture and articulated with vertical and horizontal reglets to provide
additional visual interest.
Architectural Details. The new buildings have simple detailing with little opportunity for
decoration, ornamentation, or other details of elaborate workmanship. Nevertheless, the
design and treatment of exterior surfaces, use of metal awnings and inset metal
balconies, and simple fiber cement door and window trim provide an appropriate level of
visual interest and quality of design. The need to address the base flood level provides
for a raised ground floor level, entry, and deck areas.
Residential Buildings. New buildings proposed for this site comply with the development
standards applicable to the Medium-High Residential (R-3) Zone (notwithstanding a
request for upper-level setback encroachments for the taller building), maintaining the
prevailing spacing, scale, setbacks and character of existing development in the vicinity.
Although new construction is not in a traditional architectural house style, the site is
situated at a transition to a block of Osos Street (between Islay and Leff) that is
characterized by a mix of commercial buildings and larger residential buildings of more
vernacular styles. Durable, easily maintained metal and wood materials are used for
fencing, railing, and similar site features, and utility, trash enclosure, and parking areas
are located interior to the site, screened by fencing and structures.
4.0 ENVIRONMENTAL REVIEW
The project is categorically exempt from the
provisions of the California Environmental Quality Act
(CEQA). It consists of Infill Development consistent
with the Medium High Density land use designation
and applicable policies described in the City’s
General Plan, consistent with standards and
limitations described in Zoning Regulations for the
Medium-High Density (R-3) Zone, occurs on a project
site of less than five acres substantially surrounded
by urban uses with no value as habitat for
endangered, rare or threatened species, would not
result in any significant effects relating to traffic, noise, air quality, or water quality, and
can be adequately served by all required utilities and public services , as described in
CEQA Guidelines § 15332.

5.2.5 Railroad Historic District
Setting
Established in 1998, the Railroad Historic District boundaries follow the historic boundaries of
the Southern Pacific rail yard. The district is bounded by railroad right-of-way on the east, from
Johnson Avenue on the north to Orcutt Road on the south, on the northwest generally by Leff
Street, and on the west by Broad Street and the railroad right-of-way. The district includes a
residential and commercial area on the west side of the tracks, and abuts the Old Town Historic
District along its northwest and north boundary. The Southern Pacific (or “Espee”) standard
gauge railroad arrived in San Luis Obispo on May 4th, 1894. By 1901, San Luis Obispo was a
part of the completed railroad line from San Francisco to Los Angeles, and served as the main
layover and maintenance yard for the coastal route. The SP railroad operated in tandem with the
older, narrow gauge railroad, the Pacific Coast Railway, or PCR. The PCR was a regional
railway with a station on South and Higuera - the development of a spur line along South
connected the PCR with the Southern Pacific rail yard. The Railroad District is a part of nine
older subdivisions: the Beebee Phillips Tract recorded in 1874, Fairview Addition recorded in
1887, Haskins Tract recorded in 1887, Ingleside Homestead Tract recorded in 1887, the McBride
Tract recorded in 1887, the Loomis Addition recorded in 1887, Maymont Addition recorded in
1888, Loomis and Osgood Re-subdivision recorded in 1894 and the Imperial Addition recorded
in 1897. The Railroad District has an area of 80.7 acres or 0.126 square miles and 38 designated
historic structures.
Development in the Railroad Historic District corresponded to the development of the Southern
Pacific Railroad yard. Commercial and residential buildings were constructed to accommodate
railway workers, freight and passengers, and employees of Southern Pacific and related
businesses. Surviving historic structures date from 1894 to 1945, corresponding with the peak
activity of the rail yard and the district’s period of significance, and most were constructed from
1894 to 1920. The buildings were laid out in a fairly regular grid near the station,
accommodating the curve of the rail line and the diagonal path of Santa Barbara. South of
Upham the lots are much larger to accommodate the railroad structures.
Site Features and Characteristics
Common site features/characteristics
include:
A. Commercial buildings located at
back of sidewalk with zero street
setbacks
B. Front building facades oriented
parallel to street
C. Finish floors at grade
D. Recessed front entries oriented
toward the street

Architectural Character
The predominant architectural style within the Railroad Historic District is Railroad Vernacular.
Railroad Vernacular is characterized by simplicity of form and detailing, with wood, brick or
plaster siding, and is a style favored by railroad construction for its easy construction. As a
practical vernacular style it also incorporates other elements of other architectural styles
including Classical Revival and Mission Revival. Although many of the buildings within the
district were not constructed by the railroad, their use of Railroad Vernacular styles design
reflects the unifying focus of the district. The buildings in the Railroad District are a mix of
simple, yet elegant houses and practical, industrial-oriented commercial buildings, which create a
distinctive neighborhood. The architectural character and important historical elements are
described in the Railroad District Plan. The Plan includes design guidelines that illustrate
architecturally compatible design treatments for new development.
Predominant architectural details include:
A. One- and two-story buildings
predominate
B. Gable and some hip roof types of low to
medium pitch, occasionally with
parapets
C. Predominantly painted wood siding,
with some masonry or smooth plaster
wall siding
D. Traditional fenestration, such as double-
hung, wood sash windows, and fixed
divided light windows
E. Rectilinear massing, with equal or lesser
volume on second floor
F. Simple detailing often along the roof
line including brackets

Individually Contributing Elements in the Railroad District
Not all designated historic resources in the Railroad Historic District were built during the
District’s period of significance, 1894-1945. These buildings were constructed outside of the
period of significance, generally do not exhibit the signature architectural elements described
above, but do contribute to the historic character of San Luis Obispo in their own right based on
age, architectural style or historical association. By virtue of their significance, these resources
also merit preservation.
For example, the Tribune Republic Building, built in 1873, is believed to be the earliest
surviving wood commercial building in San Luis Obispo and has been placed on the City’s
Master List and the National Register of Historic Places for its association with the City’s first
newspaper.
Non-Contributing Elements in the Railroad District
Non -contributing buildings are those that both do not meet the criteria outlined above and have
not achieved historical significance. Most of the post—1950 contemporary buildings in the
district fall into this latter category.
Non-contributing architectural styles,
materials or site features include:
A. Building height, form, scale or
massing which contrasts markedly
with the district’s prevailing 1 and 2-
story buildings
B. Metal, contemporary stucco or other
contemporary siding, including “faux”
architectural details or features that
contrast markedly with traditional
railroad vernacular forms, details and
materials
C. Asymmetrical arrangement of doors or
windows
D. Non-recessed or offset street entries to buildings
Residential
Although the majority of the Railroad District is commercial, there is a small residential area
within it which runs along Church Street and Santa Barbara Avenue from Osos to Upham
Streets. This area was home to many railroad employees and their families.

Site features and characteristics- Residential:
A. Residential buildings with modest street
setbacks of 10 feet
B. Coach barn (garage) recessed into rear
yard
C. Front building facades oriented parallel
to street.
D. Finish floors raised 2-3 above finish
grade
E. Front entries oriented toward street,
with prominent walk, stairs and porch
The houses within the residential district are
modest, which reflects their early working class
occupants. Within the district are two hotels,
the Call/Parkview Hotel at 1703 Santa Barbara and the Park/Reidy Hotel at 1815 Osos which
once served as boarding houses for railroad workers. These vernacular buildings have decorative
elements from several styles including Craftsman Bungalow, Classical Revival and Folk
Victorian.
Architectural features- Residential:
A. One and two story buildings
B. Gable and some hip roof types of low
to medium pitch
C. Painted wood surface material,
occasionally smooth stucco wall
siding
D. Traditional fenestration, such as
double-hung, wood sash windows,
ornamental front doors, wood screen

ARCHITECTURAL REVIEW (MINOR), 08/23/23Prepared by TEN OVER STUDIO1601 OSOS STThe project aims to maximize the usability of .1 acre lot by integrating seven new dwelling units into a mixed use neighborhood in the core of San Luis Obipso's Historic Railroad District. The propsed residential building's simple, rectilinear, modern carraige house style design creates a sensitive intersection between the site's commercial and residential surroundings. The two story Duplex addition takes design influence from the existing commercial unit and creates a smooth transition in building scale from the exsiting single story commerical to the new three story residential building.Page 145 of 198

Architectural Guidelines for the Railroad District
San Luis Obispo has adopted citywide architectural guidelines which apply to new buildings, significant remodels, site improvements, and public area im-
provements. The Railroad District Architectural Guidelines are to supplement the citywide architectural guidelines and are to be applied in a similar manner,
except that they apply only to the Railroad District as shown in Figure 4. Within this area, new development, remodels and additions, site improvements,
and publicly-funded projects should follow these guidelines. Property owners, developers, designers, City staff and advisory bodies, such as the Cultural
Heritage Committee, Architectural Review Commission and the Planning Commission will use these guidelines to review development projects, consistent
with Municipal Code Chapter 2.48.
Many of the older buildings in the Railroad District are generally described as “Railroad Vernacular” buildings. A variety of architectural styles fall under this
category. Some of the more common architectural elements exemplifying this architectural style are illustrated in this document. These examples provide a
“menu” of architectural elements which can be incorporated into new development projects in the Railroad District. New buildings need not include all of these
elements, nor be designed to be a replica of a historic building. The Cultural Heritage Committee and Architectural Review Commission interpret the guidelines
and will consider contemporary architectural styles which are consistent with these guidelines and which complement the District’s historic character.
Examples of different architectural styles that may generally be referred to as Railroad Vernacular.

architectural guidelines
1. Simple, rectilinear building forms should
predominate.
2. Lower building level (ground floor) massing
should be horizontal with equal or lesser volume
on upper levels.
3. Use medium-sloping roofs, generally 4:12 - 8:12
pitch.
4. False-front buildings with shed roofs and parapets
may be used.
5. Gable, hip, and shed roof forms are typical, with
some combinations and minor variations.
6. Deep roof overhangs are common, particularly
for commercial buildings, at ground floor level.
7. Roof overhangs are typically supported with
exposed, diagonal support braces or decorative
brackets.
8. Simple gable, hipped, or Dutch hipped dormers
can be used for light or ventilation.
Building Form, Massing, and
Roof Lines
Shed roofed buildings help increase light and ventilation in
industrial buildings and contribute to the character of the
District.

Doors and Windows
1. Doors and windows should emphasize
symmetry and be vertically oriented.
2. Doors should typically be single or multi-
panel, occasionally with glazing and transom
windows above doors.
3. Windows are typically fixed, or double hung,
often with divided lites.
4. Windows are often grouped in multiples of
two or three, side by side.
5. Horizontal windows may be used with
divided lites and may be grouped.
6. Doors and windows should generally have
wood or plaster trim.
7. Windows in plaster buildings may be arched
and recessed, sometimes with wood trim.

Surface Treatment and Colors
Wood Buildings
1. Horizontal and vertical shiplap, “V-rustic” siding, or board and batten siding are common.
2. Shingles are often used as infill siding for gable ends or above doors and windows, away
from people contact areas.
3. Wood trim is commonly used to create decorative patterns.
4. Siding may change direction in the same plane to provide variety in surface pattern and
texture.
5. Horizontal trim may be used to separate board patterns or to create a wainscot effect.
6. Emphasize lighter earthtones such as tan and ochre, with contrasting trim and roof colors.
Accent colors are generally low chroma and relatively neutral colors.
7. Common roof materials include composition shingle, rolled asphalt roofing, built-up roofing,
low profile corrugated metal, and barrel tile. Barrel tile is occasionally used to accent ridges
on composition shingle roofs.
8. If chimneys are used, they are generally of brick with simple ornamentation at the cap.
9. Foundations are commonly emphasized with brick, stone, or plaster wainscot.
Plaster/Masonry Buildings
1. Brick is commonly used as an exterior building material.
2. Plaster should have a smooth, hand-finished appearance. Stucco or heavily-troweled finishes
should be avoided.
3. Plaster buildings are usually white or off-white with accent plaster colors at wainscot or in
accent areas. Accent colors should be pastel or low chroma.
4. Plaster building wainscots at lower walls may be flush and painted simply, or dimensional.
5. Roof material is generally barrel tile, or sometimes “diamond pattern” or similar decorative
composition shingle roofing with accent tiles. Built-up roofing is also common.
Auxiliary Buildings
1. Auxiliary buildings may be sided with the same material as adjacent principle buildings on
the same lot; or if solitary, wood or unpainted corrugated metal panel siding is common.
2. Roofs should generally consist of composition shingles or corrugated metal panels.
Wood or corrugated metal panel siding, or plaster are
common surfaces. Stucco should be avoided.

Architectural Details
1. Commercial buildings generally have simple detailing with little decoration or ornamentation.
2. Some carved shapes are used for rafter tiles, brackets, roof eave bracing, and roof gutters.
3. More elaborate ornamentation is common on masonry buildings, including parapet details, towers or decorative cornices or quoins.
4. Finials and decorative wood work is sometimes used at roof ridges.
5. Plaster corners are typically rounded.
6. Connection details, particularly for large structures, are visually emphasized, sometimes with timber connectors, bolts, brackets or other similar
hardware.
7. Linear raised decks or platforms common with structures with raised floors.
8. Exterior-mounted mechanical equipment, including HVAC units, fire suppression equipment, and antennas should be architecturally
screened.
Signs and Awnings
1. Signage should generally be non-illuminated. Spot lighting should be used where lighting is needed.
2. Signs should either be monument type, or painted or applied individual letters directly on building walls.
3. The City will consider exceptions to Sign Regulations to encourage historic sign designs and placement.
4. Signs within the Railroad right-of-way should be simple, clearly legible, and reflect historical railroad graphic standards and colors.

Site and Public Area Improvements
1. Site improvements, such as seating areas, bollards, stairs, ramps and
walkways should be designed to complement the railroad architectural
character. Public improvements such as, but not limited to, traffic controls,
street lights, signs, benches and trash containers should be designed
in a historic character similar to styles prevalent in the Railroad District
before 1950, and they shall be approved by the Architectural Review
Commission before the final design is completed.
2. Lighting in the depot area should closely resemble the design of the
railroad era downlights used in the passenger platform area. All lighting
should be shielded to prevent glare onto adjacent properties.
3. Pole lights, bollards, information signs, trees and other vertical landscape
features should be used to create repetitive, linear, rhythmic elements along
the railroad corridor to complement the District’s historic character.
4. In the passenger depot and other high traffic areas, an open-style,
decorative fencing and/or rails should be used. In non-traffic areas
abutting the railroad right-of-way, storage areas, construction yards and
similar uses should be visually screened from the railroad right-of-way.
Appropriate fencing materials include vinyl-clad chainlink, steel picket,
wrought iron and other similar, low-maintenance open fences which
discourage graffiti. Combination wood and metal rails may also be
appropriate. Solid, plain masonry and concrete, walls; and residential-style
wood fencing should generally be avoided or accompanied by climbing
vines to discourage graffiti.
5. Security fencing, such as barbed or concertina wire, should be minimized
where visible from the railroad yard or a public way. The Architectural
Review Commission may approve the use of security fencing when
such materials are visually compatible with their surroundings and used
sparingly.
6. Public sidewalks along portions of Osos, Santa Barbara, Church, Emily,
High, and Roundhouse streets within the Railroad District should be a
City-approved wood boardwalk design.
7. Decorative paving using patterns or integral color is encouraged in specific
areas to define or clarify circulation or activity areas.
8. Pedestrian bridges, underpasses and other transportation- or rail-related
structures should use historic materials and design elements. Possible
elements include: metal and heavy timber structural supports with
exposed connectors; local stone or brick foundations or bases; and use
of spur track, railroad ties or other railroad equipment and materials.

Landscape Design
1. Planting areas should be provided: 1)
in or adjacent to outdoor public use
areas; 2) along the railroad right-of-way
to screen storage yards, solid walls or
fences, or unsightly views; and along
public street parkways.
2. Planting should be used sparingly to
define pedestrian use areas, waiting
areas, and other high visibility/high traffic
areas that can be regularly maintained.
3. Planting within the railroad right-of-way
should be low-profile, generally not over
12-15 feet tall, to provide screening and
color.
4. Tree planting within or immediately
adjacent to the railroad right-of-way
should emphasize open, medium-
height canopy trees; and trees should
be selected and placed to preserve and
frame scenic vistas of the Morros and
surrounding hillsides. Within the historic
Railroad Yard, Canary Island Date Palms
or equal should be used to extend the
Southern Pacific theme as an entry
statement for the Railroad District.

Residential Buildings
1. New residential buildings should generally maintain the prevailing
spacing, scale, setbacks and character of older houses and
apartments along Osos, Santa Barbara, and Church streets.
2. New houses and apartments should generally reflect the District’s
predominant architectural styles, which include, but are not limited
to California Bungalow, Spanish Revival, Italianate, and Victorian.
New development should include architectural features common to
the particular architectural style.
3. Raised foundations, covered front porches, and recessed front entries
are common residential architectural features.
4. Architectural detailing at roof gable ends, roof eaves, windows, doors,
railings, foundations, and chimneys should be emphasized, and be
used consistently on all building elevations.
5. Site features such as exterior lighting, paving, walls, fences, railings
and landscaping should be selected for ease of maintenance and for
compatibility with traditional designs and materials.
6. Utility areas, trash enclosures, and uncovered parking spaces (except
in driveways) should generally be screened with landscaping and/or
low walls or fencing.
Remodels and Additions
1. Remodels and additions should be sensitive to the building’s original
character and to the character of adjacent buildings. Roof pitch,
building form and materials, windows and doors, and architectural
detailing should, where possible, match existing building features
and be compatible with the scale, spacing, setbacks and massing
of adjacent buildings within the Railroad Historic District.
2. Building colors and materials should complement the building’s
historic character. When remodeling designated historic structures,
materials and details should be used honestly such as wood sash
windows to replace existing wood windows. Simulated or veneer
products should generally be avoided.
3. When remodeling or adding on to designated historic structures,
property owners and designers are encouraged to follow the U.S.
Secretary of the Interior’s Guidelines for Preserving, Rehabilitating,
Restoring, and Reconstructing Historic Buildings.

Construction in Historic Districts
New structures in historic districts shall be designed to be architecturally
compatible with the district’s prevailing historic character as measured by
their consistency with the scale, massing, rhythm, signature architectural
elements, exterior materials, siting and street yard setbacks of the
district's historic structures. New structures are not required to copy or
imitate historic structures, or seek to create the illusion that a new
building is historic..
§ 3.2.1 (c)
Architecturally
compatible
development within
Historic Districts
The CHC reviews development in historic districts for architectural
compatibility with nearby historic resources, and for consistency with
applicable design and preservation policies, standards, and historic district
descriptions in Section 5.2. New development should not sharply contrast
with, significantly block public views of, or visually detract from, the
historic architectural character of historically designated structures
located adjacent to the property to be developed, or detract from the
prevailing historic architectural character of the historic district.
