City of Milton
ARTICLE 1. GENERAL
1.1 INTENT
The intent and purpose of This Code is to enable and support the implementation of the following policies:
a. That Crabapple is an important center for high-quality, mixed-use development in the City of Milton as
established in the Crabapple Visioning Study and the City of Milton 2030 Comprehensive Plan.
b. That within Crabapple, ordinary activities of daily life should occur within walking or bicycling distance of
most dwellings.
c. That interconnected networks of thoroughfares should be designed to disperse traffic and reduce the
length of automobile trips.
d. That a range of housing options should be provided to accommodate different needs in the community.
e. That development should be concentrated in areas served by existing infrastructure and discouraged in
areas lacking it.
f. That development patterns should enable children to walk or bicycle to school.
g. That a range of open spaces including parks, squares , playgrounds, and preserved rural areas should
be distributed throughout Crabapple.
h. That buildings and landscaping should contribute to the physical definition of thoroughfares as civic
places.
i. That development should adequately accommodate automobiles while respecting the pedestrian and the
spatial form of public areas.
j. That community design should reinforce safe environments, but not at the expense of accessibility.
k. That architecture and landscape design should grow from the local climate, topography, history, and
building practices.
I. That civic buildings and public gathering places should be provided as locations that reinforce community
identity and support self-governance.
m. That civic buildings should be distinctive and appropriate to a role more important than the other buildings
that constitute the fabric of the area.
n. That the preservation and renewal of historic buildings should be facilitated.
o. That the harmonious and orderly growth of Crabapple should be secured through form-based codes
rather than traditional zoning .

1.6 DENSITY CALCULATIONS
1.6.1 Density shall be expressed in building units per acre as specified for each Transect Zone by Table 10
section a.
1.6.2 The maximum Density of a site shall be calculated by multiplying the Transect Zone's Density identified in
Table 10 section a by the Gross Site Area. Where a site includes multiple Transect Zones, each shall be
calculated independently. The area of new Thoroughfares and Civic Spaces on the site shall be allocated to
the closest Transect Zone(s) on the site. Where a Thoroughfare or Civic Space adjoins multiple Transect
Zones, their area shall be proportionally allocated to the adjoining zones.
1.6.3 Where a site is subdivided into lots, a lot's Density may exceed the Density of the Transect Zone within
which it lies, provided that the maximum Density of the Transect Zone for the site as whole as established in
Section 1.6.2 is not exceeded.
1.6.4 Building units shall be exchanged for Functions at the following rates as established in Table 8B:
a. Residential : 1 dwelling unit for each building unit.
b. Lodging: 2 guest rooms for each building unit.
c. Office: 2,250 square feet for each building unit.
d. Retail: 2,250 square feet for each building unit.
e. Other: 2,250 square feet for each building unit.
1.6.5 Where the exchange of building units for Functions results in a fraction, the fraction shall be rounded down to
the nearest whole number of dwelling units, guest rooms, or square feet as established in Section 1.6.4 .
1.6.6 Accessory Units do not count toward Density calculations.
1.6.7 Civic Buildings do not count towards Density calculations.
1.6.8 Senior housing units do not count toward Density calculations, but are subject to Density limitations
established in Section 64-1834.
1.6.9 Contributing historic structures in a historic district or property do not count towards Density calculations.
1.6.1 0 The number of Building Units allowed on a site may be increased by two Building Units for every one parking
space that meets one of the following conditions:
a. Is located within a Parking Structure having two or more above-ground stories, including the ground level.
b. Is located within a Parking Structure having one or more below-ground stories .
c. Is available for exclusive use by off-site Retail, Restaurant, Civic, or Office Functions within a straight-

line radius of 600 horizontal feet from the parking space to the public entrance of the establishment.
Parking spaces meeting two or more of the above conditions shall only be considered as meeting one
condition for the purpose of the Building Unit bonus.
1.6.11 The Base Density of a site may be increased by the Transfer of Development Rights (TOR) up to the amount
specified for each zone by Table 10 section a subject to the provisions of Section 1. 7
1.7 TRANSFER OF DEVELOPMENT RIGHTS
1. 7.1 Purpose: The TOR mechanism is intended to encourage the voluntary redirection of future growth from areas
where Milton wants reduced development into areas designated for development. Landowners can voluntarily
choose to have their properties considered as either Open Space TOR Sending Sites or Park/Greenway TOR
Sending Sites. Open Space TOR Sending Sites remain under private ownership subject to a conservation
easement permanently limiting future development. Park/Greenway TOR Sending Sites are transferred from
private ownership to the City of Milton or otherwise secured for public access in a manner acceptable to the
City. In return for voluntarily participating in the TOR program, private property owners receive TORs which
can be transferred for use at designated TOR Receiving Sites.
1.7.2 TOR Sending Site Criteria
a. Open Space TOR Sending Sites shall be a minimum of 5 acres in size, shall be zoned T2 within This
District or AG-1 outside of This District and shall contain natural or agricultural features whose retention
would implement Milton's goals for maintaining significant environmental areas , rural character and open
space. Parcels shall not qualify if the restrictions that would be imposed by a conservation easement
have already been established by a preexisting easement or similar instrument.
b. Park/Greenway TOR Sending Sites shall be a minimum of one acre in size, unoccupied by any residences
or other improvements that would render the site unusable for public access and shall be designated as
suitable for Park, Greenway, Civic Space, trail or other public recreational uses in a plan or code adopted
by the City. Parcels in public ownership prior to the effective date of This Code shall not qualify as TOR
Sending Sites. However, parcels that the City buys for Parks and Greenways after the effective date of
This Code meet the criteria for Park/Greenway TOR Sending sites.
1.7.3 TOR Sending Site Approval Process
5
a. Open Space TOR Sending Sites: Property owners may offer their land as Open Space TOR Sending
Sites using application forms provided by the community development department. If the community
development director finds that the proposed property meets the criteria, he/she shall approve the
application and oversee the execution and recordation of a permanent conservation easement, approved
by the community development director, that limits future development of the sending site to a density of
no more than one dwelling per parcel or one dwelling per full25 acres, whichever Density is greater. The
easement shall specify that all other uses, building requirements and activities shall be controlled by the
provisions of the T2 zone for parcels within This District and the provisions of the AG-1 zoning district for
parcels outside of This District.
b. Park/Greenway TOR Sending Sites: Property owners may offer their land as Park/Greenway TOR
Sending Sites using application forms provided by the community development department. If the
property owner proposes to transfer title to Milton, the change of ownership shall pertain to the entire
parcel. If the community development director finds that the proposed property meets the criteria for a
Park/Greenway TOR Sending Site, he/she shall approve the application and submit the transfer of title to
the City of Milton or an agency/organization authorized by the City Council for approval. A permanent

CRABAPPLE FORM-BASED CODE
City of Milton
public access easement approved by the community development director may be used instead of title
transfer if the proposed easement would implement all preservation and public recreational goals for the
site in question , subject to the approval of the City Council. This easement may apply to all or a portion
of a single parcel as long as the portion subject to the easement is at least one acre in size. If a
Park/Greenway TOR Sending Site is secured by easement rather than City ownership, the easement
shall permanently prohibit all development, shall preclude any improvements that would impede site use
for public purposes and shall specify that all other uses and activities will be controlled by the provisions
of the T2 for parcels within This District or the provisions of the AG-1 zoning district for parcels outside
the This District.
1.7.4 TOR Allocation
a. Open Space TOR Sending Sites: Upon recordation of an approved conservation easement, the
community development director shall deduct the area of land precluded from development by preexisting
easements and issue TORs to the owners of Open Space TOR Sending Sites using the following formula :
i. One TOR per full acre of Unconstrained Land
ii. Plus one TOR per four full acres of Constrained Land
iii. Plus one TOR per each full five acres of land subtotaled under i. and ii. in excess of five acres
b. Park/Greenway TOR Sending Sites : Upon title transfer or recordation of an approved public access
easement, the community development director shall deduct the area of land precluded from
development by preexisting easements and issue Transferable Development Rights to the owners of
Park/Greenway TOR Sending Sites using the following two-step process.
Step One: calculate the total number of TORs produced by i, ii and iii below:
i. One TOR per full acre of Unconstrained Land
ii. Plus one TOR per four full acres of Constrained Land
iii. Plus one TOR per each full five acres of land subtotaled under i. and ii. in excess of five acres
Step Two:
Multiply the total from Step One by a factor of 1.25
c. Civic Space TOR Sending Sites: Upon title transfer or recordation of an approved public access
easement, the community development director shall deduct the area of land precluded from
development by preexisting easements and issue Transferable Development Rights to the owners of
Parks/Greenways TOR Sending Sites designated as suitable for Civic Spaces in an adopted plan or
code using the following two-step process.
Step One: calculate the total number of TORs produced by i, ii and iii below:
i. One TOR per full acre of Unconstrained Land
ii. Plus one TOR per four full acres of Constrained Land
iii. Plus one TOR per each full five acres of land subtotaled under i. and ii. in excess of five acres
Step Two:
Multiply the total from Step One by a factor of 1.5.
1.7.5 TOR Transfers: The community development director shall establish and administer a process for
documenting and monitoring the issuance, transfer and permanent extinguishment of TORs when they are
used to increase density in a TOR Receiving Site development. TOR Sending Site property owners who are
issued TORs may retain them, transfer them directly to TOR Receiving Site developers or transfer them to
intermediaries who may also retain them or transfer them to TOR Receiving Site developers. The City of Milton

may but is not obligated to buy, hold and resell TDRs. The City may also sever TDRs from land that it buys
after the effective date of this ord inance for Parks and Greenways and sell these TDRs for use in TDR
Receiving Site developments. The price paid for TDRs is determined by negotiation between TDR buyers and
sellers.
1.7.6 TDR Receiving Sites : TDRs may be transferred to the TDR Receiving Sites designated by This Code and any
additional TDR Receiving Sites that may subsequently be designated by the City. TDR Receiving Site owners
may build at or below the Base Densities established by code without any use of TDRs. However, owners
who choose to do so may exceed the Base Densities and achieve the established maximum densities at the
transfer ratio set forth in Section 1.7.7.
1.7.7 TDR Transfer Ratio: Pursuant to This Code, developers of projects on TDR Receiving Sites may use the TDR
to exceed Base Densities and achieve the maximum code-allowed Density at the transfer ratio of two building
units per full TDR. Building Units shall be exchanged for Functions as set forth in Section 1.6.4.
1.7.8 Unified Sending/Receiving Site: A TDR Sending Site and a TDR Receiving Site may occur on a single parcel
if the respective portions of the parcel meet all criteria . TDRs from the Sending Site portion of the parcel shall
be allocated using the formula provided in 1. 7.4 except TDRs shall not be granted open space and Greenway
dedications that are required as a condition of site development. TDRs from the TDR Sending Site portion of
the parcel may be transferred to the TDR Receiving Site portion of the parcel, transferred to a separate TDR
Receiving Site or to any combination of on-site and off-site TDR Receiving Sites.
1.7.9 Compliance Requirements
7
a. When the use of TDR results in divisions of land, TDR compliance shall occur prior to final subdivision
map approval.
b. When the use of TDR results in additional Density without a division of land, TDR compliance shall occur
prior to building permit issuance.
c. In no event shall any component of this TDR program have application to any TDR Sending Site or TDR
Receiving Site outside the jurisdictional boundary of the City of Milton .

TABLE 6: Building Placement This table approximates the location of the structure relative to the boundaries of each individual Lot, establishing suitable basic
building types for each Transect Zone.
a. Edgeyard: A building that occupies the center of its lot with Setbacks on all sides. This is the least
urban of types as the front yard sets it back from the Frontage, while the side yards weaken the
spatial definition of the public Thoroughfare space. The front yard is intended to be visually
continuous with the yards of adjacent buildings. The rear yard can be secured for privacy by fences
and a well placed Backbuilding and/or Outbuilding.
b. Sideyard: A building that occupies one side of the lot with the Setback to the other side. A shallow
Frontage Setback defines a more urban condition. If the adjacent building is similar with a blank side
wall, the yard can be quite private. This type permits systematic climatic orientation in response to the
sun or the breeze. If a Sideyard House abuts a neighboring Sideyard House, the type is known as a
Twin or double house. Energy costs, and sometimes noise, are reduced by sharing a party wall in this
disposition.
c. Rearyard: A building that occupies the full Frontage, leaving the rear of the lot as the sole yard. This
is a very urban type as the continuous Facade steadily defines the public Thoroughfare. The rear
Elevations may be articulated for functional purposes. In its Residential form, this type is the
Rowhouse. For its Commercial form, the rear yard can accommodate substantial parking.
d. Courtyard: A building that occupies the boundaries of its lot while internally defining one or more
private patios. This is the most urban of types, as it is able to shield the private realm from all sides
while strongly defining the public Thoroughfare. Because of its ability to accomodate incompatible
activities, masking them from all sides, it is recommended for workshops, Lodging and schools. The
high security provided by the continuous enclosure is useful for crime-prone areas.

TABLE 7: Private Frontages. The Private Frontage is the areas between the building Facades and the lot lines.
a. Common Yard: a planted Frontage wherein the Fayade is
set back substantially from the Frontage Line. The front yard
created remains unfenced and is visually continuous with
adjacent yards, supporting a common landscape. The deep
Setback provides a buffer from the higher speed
Thoroughfares.
b. Porch & Fence: a planted Frontage where the Fayade is set
back from the Frontage Line with an attached porch permitted
to Encroach. A fence, wall, or hedge at the Frontage Line
maintains street spatial definition. Porches shall be no less
than 8 feet deep.
c. Terrace or Lightwell: a frontage wherein the Fayade is
setback back from the Frontage Line by an elevated terrace
or sunken Lightwell. This type buffers Residential use from
urban Sidewalks and removes the private yard from public
encroachment. Terraces are suitable for conversion to
outdoor cafes. Syn: Dooryard.
d. Forecourt: a Frontage wherein the Fayade is close to the
Frontage Line and the central portion is set back. The
forecourt created is suitable for vehicular drop-offs. This type
should be allocated in conjunction with other Frontage types.
Large trees within the Forecourts may overhang the
Sidewalks.
e. Stoop: a Frontage wherein the Fayade is aligned close to
the Frontage Line with the first Story elevated from the
Sidewalk sufficiently to ensure privacy for the windows. The
entrance is usually an exterior stair and landing. This type is
recommended for ground-floor Residential use. Stoops shall
be no less than 30 inches deep.
f. Shopfront: a Frontage wherein the Fayade is aligned close
to the Frontage Line with the building entrance at Sidewalk
grade. This type is conventional for Retail use. It has glazing
on the Sidewalk level and an awning that should overlap the
Sidewalk to within 2 feet of the Curb. Syn: Retail Frontage.
g. Gallery: a Frontage wherein the Fayade is aligned with the
Frontage Line with an attached cantilevered shed or
lightweight colonnade overlapping the Sidewalk. This type is
conventional for Retail use. The Gallery should be no less
than 1 0 feet wide and should overlap the sidewalk to within 2
feet of the Curb.

ARTICLE 7. ARCHITECTURAL STYLES
7.1.1 This Section provides an overview of the seven architectural styles and their colors set forth in Section 4.16.2.
Because the execution of specific styles can vary, the description/definition of each style can vary and therefore, the
information contained in this article may not be all inclusive.
52
A. ARCHITECTURAL STYLES
Vernacular: With origins in Elizabethan England and influenced by Native American and African American
traditions , the Vernacular tradition in the South is the essence of beauty, function , and simplicity. It is a
powerful building type, perhaps the most indigenous to America. Dating from the arrival of the first settlers, it
was recycled into the fabric of later styles and has never been fully abandoned . Vernacular forms exhibit
natural composition, never decorative or academic, but relating to a relaxed logic. Materiality rules, as building
materials are used in their most raw, pure, forms, with ornament reduced to mere gesture, executed in the
same raw materials.
Essential elements include simple masses, many times saltbox and catslide, with additions and appendages.
Almost without exception, roofs are gabled, with gables rarely facing the front. Shed roofs over full-length
porches or enclosed additions are common . Gable-end chimneys are prominent. Windows are of similar sizes,
spaced in a balanced but not overly rigid composition, and are generally non-ornamental. Window spacing
relating to room arrangement is often independent of column or post spacing, which relates to the actual porch
structure. Modest stylistic detailing is Federal and Greek Revival, with elements of ltalianate and Carpenter
Gothic. Ceiling heights range from 9 feet to 12 feet for commercial buildings, and 7 feet to 10 feet for houses.
One-story Vernacular cottages may have so-called travelers rooms on either side of a front porch, featuring
ceilings as low as 7 feet. Frugality rules Vernacular architecture. Hand made brick, wood horizontal lap siding,
flush T&G plank siding under porches , wood-shingle and standing-seam roofs, and brick and/or stone
chimneys are the typical features found in early architecture. Later forms are sometimes roofed in corrugated
or 5-V galvanized metal.
Typical exterior colors for earlier buildings include slate blue and earth tones such as terra cotta, taupe, and
brown. Later works are typically whitewashed.
Because Vernacular is not truly a style but a local building tradition , its form never hybridized with nineteenth
century styles. Stylistic detailing is applied to the building in a superficial manner.
Greek Revival: Of the Romantic styles favored in the nineteenth century, perhaps none was more popular
than Greek Revival. Dominant from about 1830 to 1860 in the South, the style symbolized the affinity
Americans felt with the ideals of Greek democracy.
The style was easy to construct in wood or masonry due to its Spartan forms and details. Forms are boxy with
consistent cornice lines and low-pitched gabled or hipped roofs. Gables can be side or front facing.
In the South, Greek detailing and full-width front porticos are often married to Vernacular forms , taking the
form of a classical billboard , which is one of the more charming aspects of this region's native architecture.
Porches vary in prominence, being either the fabled Southern full-width two-story version or the less
ostentatious one-story version or even the smaller stoop variety, which is equally dignified. Fenestration
features include rectangular sash and doors with bold , plain casings and horizontal cornices. Chimneys, being

non-Classical, are thoroughly de-emphasized. Columns that are always round in true Greek architecture are
usually simplified into square adaptations. Classical details are large and bold as opposed to the earlier, mild-
mannered Adam Style, with wide, prominent entablature with Greek Doric columns being the main hallmark
of the style . When decoration is desired, it is executed with Greek key fretwork, and vernacularized classical
profiles.
Paint colors for siding and trim are typically white, cream , and light grey with shutters tinted black. Window
sash are white or black . Wood-mold brick is in the red to earth range.
ltalianate: The ltalianate style became popular in America around 1840 and flourished especially rapidly in
the 1850s. As its name implies, the Renaissance houses of Italy are its inspiration. The style is picturesque
or romantic as opposed to the more disciplined Greek Revival style. Broad, bracketed cornices on shallow
hipped or gabled roofs; attic windows; tall windows that are frequently arched and clustered; iron balconies;
massive entrance doors; clustered porch columns; Renaissance details; and tall ceilings are hallmarks of this
style. Facades may be symmetrical and somewhat dignified, or asymmetrical, with a casual, rural quality.
Chimneys are usually internal to the building mass.
In the South, there are many interpretations of the style executed in wood, with Renaissance-style ornament
adapted to local skill levels. Some versions of this style are easy to construct, especially if the building material
is brick, for then fundamental masonry techniques are used such as full or segmental arches, lintels, and load-
bearing walls.
Paint colors for siding, trim, and sashes are typically earth tones with emphasis on browns, terra cottas, and
golds. Trim colors and sashes are usually painted darker than the siding. Wood-mold brick is in the red to
earth range.
Gothic: With origins in late 18th century England, the Gothic Style, otherwise known as the Gothic Revival,
was popularized by Andrew Jackson Downing in the 1840s and 1850s. The style may be looked at as a
reaction to the classical styles so popular at the time of the Adam style or Federal style , and the Greek Revival.
With a definite nod to the whimsical, the style provided a welcome relief to the academic aesthetic of the era.
Many Americans associate the style with Grant Wood 's American Gothic, a painting depicting a rather austere
midwestern husband and wife set in front of a plain board and batten cottage with a pointed arched window.
Applied to the hall and parlor houses popular at the time, humble folk houses were transformed into medieval
fantasy with the addition of steep roofs, decorative verge boards and crockets, pointed arches, and pinnacles.
Board and batten siding, paired columnettes, and 2 over 2 windows accentuated the verticality of the look.
Old-timers sometimes naively refer to the ornamentation of the style as "gingerbread".
Many Gothic buildings dot the historic American countryside, with a special abundance in the North Georgia
area. From Rome's medieval clock tower to the Gothic cottages of Clarkesville, the Gothic style has become
inextricably fused with the American psyche.
Queen Anne: The Queen Anne Style dominated domestic American architecture from about 1880 until1900.
Popularized by the architect Richard Norman Shaw, the style was a revival of late medieval styles in England.
(The name Queen Anne, however has little or nothing to do with the reign of the English queen during the
formalistic Renaissance period.) Indigenous versions of the style usually translated into wooden-frame
structures decorated with turned spindle work and free-form Classicism, with columns, pediments, and so

forth being freely substituted for medieval ornament.
The movement was fueled in the New South by the commerce generated by the cotton industry. The forms of
the buildings themselves are a fanciful version of medieval forms . Asymmetry was the general rule with steeply
pitched roofs, front gables, and folk ornament. As opposed to the academic Adam and Greek Revival styles,
there is a deliberate effort at making the fagade three dimensional, using projecting gables and cutaway bays.
The new railroads brought pre made spindle work and bric-a-brac ornament to almost every American town
and city, resulting in the proliferation of the quintessential gingerbread house. Windows tended to be 1/1 or
2/2 with the occasional ornamental sash. Ceilings were usually very tall, starting at 1 0 feet. Examples exist of
this style in the Crabapple Community.
Colors were earthy-sage, taupe, amber, gold, and brown. Trim and sashes were usually in the darker spectrum
of the palette.
Colonial Revival: Inspired by the Centennial of 1876, the Colonial Revival thrived in the love that Americans
have for their Colonial past, especially in English and Dutch houses of the Atlantic Seaboard. In part a reaction
to the excesses of Victorian architecture, forms include simple saltbox massing , "L" configurations, catslide
roofs, and vernacular forms. Wings and additions often occur that are subordinate in scale to the primary
mass of the structure. Rooms are usually larger than their authentic Colonial predecessors and are planned
for gracious interior accommodation resulting in playful exteriors. Facades may contain front facing gables
treated in a decorative manner. Roof forms are varied in the Colonial Revival from steep Georgian types,
shallow Classical types, hips, hipped gables, Gambrels, catslides, and Southern Vernacular types. Dormers
are common roof features. Beautiful chimneys centered on gable ends terminate rooflines. Full front porches
occur, but not as often as side porches and trellises, that often take on the quality of an outdoor room.
Ceiling heights are always generous . Windows are larger than historic prototypes of early years. Americans
were not about to give up the light that they had become used to in the Victorian period . Refined stylistic
detailing includes Colloquial, Georgian, Federal, Regency, and Classical Revival elements such as columns
and pilasters, fretwork railings, entablatures, broad casings, story courses, base reliefs, etc. Exteriors are
finished in wood shingle siding, mitered lap siding, wood mould brick and worked stone. Roofs are slate, wood
shingle, French tile , and standing seam metal.
Some Colonial Revival buildings are quite decorative with Classical appl ique featuring urns, garlands, and
grotesques ornament. Other Colonial Revival buildings are hybridized with the Craftsman style and feature
straightforward construction detailing such as out-lookers supporting broad eaves, plain Tuscan columns with
no base or capital necking details, and post and beam casings.
Not all Colonial Revival houses are so freely adapted from various sources. Austere and authentic examples
exist that are almost indistinguishable from their antecedents, leaving one to ponder the construction date.
James Means, a 20th century Atlanta architect, designed Plantation Plain houses across the state of Georgia
(one notable example exists in Crabapple) with great sophistication. His colleagues , Neel Reid, and Phillip
Shutze, designed more inventive and decorative homes that are at the apex of the style in the South.
Typical exterior siding , trim , and sash colors are white, bone, and cream , with dark green or black shutters
and the occasional red door. Wood shingles are natural, stained grey or stained Jacobean black. Smooth
wood mould brick in the red to earth range, and occasionally buff to taupe range is complimented with grape
vine and lighting raked mortar joints. Stone is coursed or random and features flush , raised bead, or lightly

raked mortar joints.
Adam/Federal: The Adam or Federal style was prevalent in the South from about 1780 through 1820,
although in provincial locations; its influence lasted until around 1840. The style developed directly from
Classical Roman examples of antiquity rather than Renaissance Europe. Young America identified itself and
its government with that of Republican Rome, with a parallel movement occurring in France. The refined
ornament discovered in the archaeological digs at Pompeii heavily influenced the British architect Robert
Adam in the development of the style. Architects such as William Jay of Savannah further developed it.
Simple, austere massing and Vernacular forms are decorated with delicate classical detailing, frequently
featuring the Doric order with decorated cornices, pedimented fenestration, fine modillions and mutules under
the cornice, and entrances with fan lights and sidelights. In isolated locations, chimneys are awkwardly
domestic and prominent, while in urban locations, they are minimally formalized . Exterior cladding materials
are usually clapboards but are sometimes fine brickwork with cut jack arches and keystones. Classical
detailing is deliberately scaled down. Facades are intentionally understated and plain. Emphasis is placed on
the frontispiece and on the fine tailoring of the building. Windows are large and regularly spaced.
Paint colors for siding, trim, and sashes are typically white, cream, and light grey with shutters being tinted
black. Wood-mold brick is in the red to earth range.
B. COLORS AND FINISHES
As the architecture demands, the color palette of the City of Milton is diverse. With an emphasis on "real"
materials, whether natural or manmade, many colors and finishes should simply be left unfinished. Surfaces to
be painted should complement the architecture, never commanding too much attention. Colors must never
upstage the natural landscape.
Colors and finishes must be appropriate to the mood and style of the building . Designs that are derived from
the Vernacular style will be early 19th century color combinations, with colors such as burnt sienna; rich warm
gray, mustard and "haint" blue. Designs that take inspiration from the Greek Revival style will display crisp,
light stone colors that bespeak dignity and acknowledge their classical temple origins. Other designs that are
inspired by Queen Anne, Gothic, and ltalianate designs are complex and rich, displaying earth tones that
contrast to one another. Colonial Revival and Adams/Federal palettes take inspiration from East Coast
historic precedents with natural shingle siding trimmed in white, white or slate blue clapboard trimmed in white
with red doors, and shaker inspired colors.
The designer should research period colors and become familiar with the combinations that can be used.
C. ARCHITECTURAL STYLES ILLUSTRATED
The following are illustration of key components of the above-noted styles. Please note that the graphics
show the styles as utilized on single-family detached houses, although these styles can readily translate into
commercial or mixed-use buildings through use of stylistic detailing. Please refer to the City of Milton Historic
Preservation Design Guidelines for examples.
