STAFF REPORT
Old Coppell Design Guidelines Workshop
The Old Coppell Master Plan was discussed and accepted by City Council in April 2002. This
provided the planning/land-use analysis for the area. On May 13, 2003, Council amended the land use
component of the 1996 Comprehensive P/an and enlarged the Historic Overlay district, as proposed in
the Old Coppell Master P/an and as recommended in April 2003, by the Planning and Zoning
Commission.
The Implementation Strategy within the Old Coppell Master Plan called for Old Coppell Design
Guidelines to be drafted and adopted soon after it was accepted by the City Council. Once
adopted, these guidelines will be made available to developers to inform them of the City's
expectations for the area. The document will ensure uniformity of new construction and
preservation of the old. These guidelines are intended to be helpful in development and
redevelopment of the Historic Overlay District. These do not provide exact formulas for design,
but give an idea of what is expected. The desired results of the design guidelines are as follows:
1. To preserve and enhance the area's special historic, architectural and aesthetic
features.
2. To ensure that new construction and alterations to existing structures are compatible
with the character of the area.
3. To provide an area for shopping, dining, working, recreation and entertainment, which
will remain active during evenings and weekends.
4. To promote pedestrian activity within Old Coppell to encourage an atmosphere o£a
by-gone era.
What follows is a summary of what is contained within the document. The permitted uses and
events encouraged are consistent with the OM Coppell Master Plan. The New Construction
section ensures that development is compatible in scale, shape, orientation to the street, height,
material, color and placement on the lot. Accessory structures should be smaller in scale and
compatible in shape and materials with the main structure. Demolition should be avoided, but
where certain conditions exist, the Planning and Zoning Cormmssion and City Council may
consider it. Moving buildings into the district might be appropriate, but moving any building out
of the district should be avoided.
The On-site Requirements for New Construction, Additions, and Renovations section lists, in
alphabetical order, the various site features and the regulations pertaining to each. Driveways and
curb cuts are limited. Fence regulations are outlined, permitting picket fences in the front and
privacy fences and masonry walls in the rear. Fire safety requirements and handicap access are
outlined.
The Landscaping section is in compliance with the Zoning Ordinance in relation to plant type.
More flexibility is given to providing less perimeter landscaping as the majority of the lots will
have drives along the sides and parking in the rear. Lighting within the district will be compatible
Page I of 2 Item # 7
with the structures, but when security lighting is needed, it will need to be placed on the
secondary or rear elevation. Sign lighting will be required to be top lit with no spill over, and
streetlights will be as depicted in the approved sketch for Old Coppell. Mechanical systems will
be screened and placed on the rear fagade. Parking will need to be screened and located to the
rear of the lot. Appropriate signage will not obstruct the building features, will not be too large
and will not clutter the entry. Streetscape Furnishings (benches, trash receptacles and streetlights)
are outlined, as approved within the Old Coppell Master Plan.
Appendix A - The Architectural Design Details, outlines specific architectural features (i.e.,
awnings, doors, shutters, windows, etc...) and the details associated with historic design.
Appendix B - Repair and Maintenance gives procedures for preserving and rehabilitating various
architectural features. Appendices C, D, and E contain definitions of Procedures, Technical Items
and Architectural terms.
This is a brief summary of the items contained within the Design Guidelines. This will be brought
to the Old Coppell property owners for input in January 2005, if deemed appropriate after this
workshop. It will then be brought back to the Commission for a public heating and final
consideration, and subsequently, forwarded on to the City Council. Please review and be
prepared to discuss at Thursday's (December 16, 2004) meeting. Please also take into
consideration whether these Guidelines should be adopted as minimum standards for the district
after all the concerns are addressed, or if they should remain as Guidelines.

existing pattern of surrounding historic buildings along the street by being
similar in the following:
1. Scale (height and width) - Maximum height is to be 35' or two and
one-half stories, not including architectural elements such as cupolas
and steeples.
2. Sfiape - The massing of new buildings should De consistent with the
general massing of the existing "character defining" buildings.
3. Roof form and pitch
a. The predominant roof form should be a gable. Oable ends fronting
the street are pa~icularly appropriate based on historic precedents.
b. Exceptions to the gable roof form are most appropriate for
institutional building~ that warrant distinction. Architectural features
such as cupolas and steeples are appropriate for institutional
buildings.
c. Roofs can be screened by parapet faqades.
4. Orientation to the street
a. Building fagades should be parallel with the street.
b. AH buildings should have the main entrance fronting the pri~aW
adjacent street, and entrances should be well a~iculated through
design. Corner entrances are acceptable for corner buildingS.
c. commercial buildings should be built in close proximity to the
Sidewalk, with the exceptions being restaurants with front outdoor
dining.
d. Institutional bUildingS Ca~ De set back from the street to distinguish
themselves as special buildings.
e. Townhouses should front directly onto the Sidewalk, although a
shallow lawn can be bridged with a front stoop.
5. Location and propodion of entrances, windows, columns, porches, and
divisional bays
a. Buildings having fagades longer than those historically found in the
district should utilize distinct ve~ically oriented bays to break up the
massing.
City of Coppell 5 Historic Overlay District
Design Guidelines NEW CONSTRUCTION
b. Massing should be broken up through the use of fa~:ade plane
projections and recesses, pilasters, roofline variations, color and
material variations, and canopies.
c. All window and door openings should be vertically oriented and
should be vertically aligned between floors. Vertically oriented
windows may be ganged (grouped side-by-side) in a manner that

only alternative.
Non-Historic Buildings:
Although a building may not be historic at this time, some day it will be (it is
generally accepted that a buitding is considered "historic" when it reaches fifty
years of age). Each building period has its own details and characteristics
which contribute towards its uniqueness. Non-historic buildings should be
maintained as close to their original design as possible.

a. The hours of operation,
b. Availability of nearby parking,
c. Shared parking, and
d. Valet parking for restaurants (tandem 7'X18').
4. Parking is not permitted to be located in the front yard. Parking lots
should preferably be located behind buildings, although locations to the
sides of buildings are acceptable.
5. No property shall be converted to parking usage without City approval.
6. Asphalt is an appropriate material for parking areas within the Historic
Overlay District.
7. Parking lots should be screened through plantings of hedges, shrubs,

a Iow-impact park with playground equipment and benches is
appropriate. Landscaping should conform to the surrounding area with
as many original shade trees as possible.
Proposed playground equipment shall be reviewed by the Parks &
Recreation Department.
K. Paving
1. All on-site pavement shall comply with city design criteria and
standards for parking lots. (For City Design Criteria and Standards see
Appendix C, Section I, paragraph E(1)(j), of Ordinance No. 94643,
Subdivision Regulations, as amended.)
L. Refuse Containers
1. For institutional and commercial structures, refuse containers
(dumpsters) should be located in the rear and screened from street
view with screening/fencing or shrubbery.
2. For residential areas in the historic district, it is not permitted for a
single family home to have a permanent refuse container. If (as in the
case of a multi-family residential building), a refuse container is
necessary, it should be to the rear of the structure, or movable to the
location of garbage pickup.
3. In no case should bagged, boxed or any other garbage other than in
permanent garbage collectors be placed on the street before regular
pickup days longer than 24 hours. Refer to Article 3-5 of the Coppell

Appendix A - Architectural DesiRn Details:
A. Architectural Details and Features (Eaves, brackets, dentils, cornices,
molding, trimwork, shingles, columns, pilasters, balustrades, or any
decorative or character-defining features)
1. It is preferable to repair rather than replace an original architectural
detail or feature.
2. Substituting original materials in making repairs or in replacing missing
features should be avoided.
3. Saving deteriorated parts that must be replaced may later assist in
matching reconstructed features. Items such as wood siding, soffits,
fascias, brackets, ornamental shingles, wooden sash windows and
doors can often be restored or duplicated.
4. It is not appropriate to add details unless original and authentic to the
structure and accurately based on physical, pictorial, or historical
evidence (not conjecture) in materials, scale, location, proportions,
form and detailing.
5. Original details should not be removed or changed.

City of Coppell A-1 Historic Overlay District
Design Guidelines ARCHITECTURAL DESIGN DETAILS
Note: Awnings have traditionally been used more for function (shade) than
for decoration. In terms of decoration, awnings have fallen in and out of
favor over the years. If too many awnings are used on a structure or if
awnings are used on too many dwellings in an area, the result can be
visual clutter. For commercial buildings, historic storefronts often have
awnings and a row of commercial buildings with storefront awnings is
appropriate.
C. Chimneys
Awning used to reduce heat gain (Taken fi.om the SecretaW
of the interior's Standards for Rehabilitation)
1. Chimneys which are prominent features of the structure should not be
removed or changed, if original. Non-functional chimneys should be
maintained and not removed above the roofline. It may be appropriate
to remove nonfunctional secondary chimneys.
2. Chimneys should be repointed and cleaned according to brick and
masonry guidelines (outlined in Appendix B) to match original
materials, colors, shape, brick pattern and tooling.
3. If reconstruction of a chimney is necessary due to structural instability
or deterioration, it should be rebuilt in the original configuration.
4. Aluminum or clad chimneys are not appropriate.
Decks
1. Decks should be located on the rear and be screened from street view
with fencing and/or plants and shrubs where visible.
2. Decks should be stained or painted to match or blend with the house if
visible from street view.
3. The style of the deck and its balusters and railing should match the
style of the house.

1. Original doors and/or their entranceway surrounds, sidelights,
transoms, and detailing shall not be removed or changed.
City of Coppell A-2 Historic Overlay District
Design Guidelines ARCHITECTURAL DESIGN DETAILS
2. Replacement of missing original doors should be like or very similar to
the original in style, materials, glazing (glass area) and lights (pane
configuration)
3. Extra doors should not be added to the primary fagade or to secondary
fagades where readily visible from the street.
4. Doors, if added where inconspicuous on secondary or rear fagades,
should be similar to the original doors, not of a style or period earlier
than the original building.
5.Screen doors should be preserved and maintained if original.
6. Storm doors should be full-view and baked-on enamel or anodized

possible.
2. Downspouts should be located away from significant architectural
features on the front of the house.
3. Gutters should provide proper drainage through use of downspouts
and flashing if needed to avoid water damage to the building.
I. Light Fixtures on Commercial Buildings
1. Preserve, maintain, or repair exterior historic light fixtures. If historic
light fixtures do not exist or require replacement use concealed light
fixtures, fixtures of simple design, or fixtures appropriate to the period
of the building.
J. Porches
1. Porches on front and side facades should be maintained in their
original configuration and with original materials and detailing.
2. The porch in its original design was intended as a focal point for the
entrance to the house and should not be removed if original. Enclosure
City of Coppell A-3 Historic Overlay District
Design Guidelines ARCHITECTURAL DESIGN DETAILS
of a porch changes the overall character of a house and should be
avoided.
3. Enclosure or removal of a porch can make a building fagade seem flat.
Without a porch there is no transition from sidewalk to house. If a
porch must be enclosed, the manner of the enclosure should not
destroy the original openness, focus and transition from outside to
inside. The use of materials and details compatible with the original
character of the house is important in any necessary porch enclosure.
4. Porch details should be retained intact with repair work and
replacement of missing parts, such as columns, posts, railings,
balusters, decorative molding and trimwork, to match the original in
design, materials, scale, and placement.
5. Porch columns and rails should not be replaced by decorative wrought
_iron.
K. Roofs
1. The original shape and pitch of the roof with original features (such as
cresting, chimneys, finials, dormers, etc.) should be preserved and if
previously altered, replaced with original form and detailing.
2. The use of fiberglass shingles is appropriate if the use of original
material is not economically feasible. Dark colors are best for historic
buildings.
3. Unless original to the house, dormers should not be placed in front
rooflines. The addition of dormers to secondary and rear fagades is
appropriate if in keeping with the character and scale of the house.
4. Skylights, decks, or balconies should not be added to a roof where
visible from the street.
L. Screens
1. Screening of front porches is not appropriate.
2. Side and rear porches may be screened, although discouraged, if the
structural framework for the screen panels is minimal and the open
appearance of the porch is maintained.
3. Screen doors should be preserved and maintained if original.
4. Screen doors if new, should be wood and full-view or with structural
members aligned with those of the original door.
5. Window screens should be wood or baked-on or anodized aluminum
and fit within the window frames, not overlap the frames.
M. Security Doors & Windows
1. Security doors located on primary fagades should be simple and
without excessively ornate or decorative grillwork.

had them, the shutters are of Iouvered wood construction, and the shutters
will fit the window opening (so that if closed, they would cover the window
opening).
City of Coppell A-4 Historic Overlay District
Design Guidelines ARCHITECTURAL DESIGN DETAILS
Appropriate (Shutters fit window)
Inappropriate (Shutters do not fit)
Skylights
Skylights should not be added where.visible from the street.
Staircases
Staircases should not be added to building exteriors.
Storefronts on Commercial Buildings
1. Preserve (maintain or restore, not remove or alter) existing original
storefronts.
2. Storefront features which are deteriorated should be repaired rather
than replaced.
3. If replacement of the original storefront is necessary due to significant
deterioration, replace with features to match the original in design and
materials.
Storefronts that were remodeled after the 1940's should be rebuilt
based on pictorial or physical evidence of the original design. If the
original storefront design and features cannot be determined, install a
traditional storefront arrangement with features, materials, and
proportions typical of similar buildings of the same style or period.
5. Original storefront doors should be preserved and maintained.
Traditional entrance arrangements such as recessed or flush with the
sidewalk should be maintained.
If the original door design is unknown, replace with a single light (glass
area) door design, not solid paneled door, decorative doors, or any
kind of door based on a different historical period or style.
Preserve, maintain, or repair original display windows. If a storefront is
missing display windows, new windows should match the original in
location, design, size, and materials.
City of Coppeli A-5 Historic OverPay District
Design Guidelines ARCHITECTURAL DESIGN DETAILS
8. Display window mullion or framing should be of wood, copper, or
bronze metal.
9. Clear, rather than tinted glass should be used for storefronts. If privacy
or shade is required, use interior shades or blinds.
10. Preserve, maintain, or repair bulkheads (kickplates) where they exist.
Original bulkhead panels should not be removed.
11.Paint color on commercial buildings should conform to original color
and general streetscape. Unpainted brick should not be painted.
R. Walls
1. Wood and masonry walls original to the building should be repaired
rather than replaced.
2. Walls should be wood or a cementitious material duplicating wood.
3. Brickwork and wood siding original to the building should be preserved
but if replacement is necessary, the materials should match the original
in size, design, and texture.
S. Windows
1. Windows should be preserved in their original location, size, and
design and with their original materials and numbers of panes.
2. Window sashes should be preserved, maintained, or repaired including

5. The use of jalousie windows, awning windows or picture windows on
houses within the historic district is inappropriate. Glass block should
only be used on buildings where it may have originally existed.
6. Storm windows should be wood or aluminum with baked-on or
anodized finish and fit in the window frames, not overlap the frames.
7. Windows should not have shutters added unless the building originally
had them, the shutters are of Iouvered wood construction, and the
shutters will fit the window opening (so that if closed, they would cover
the window opening).
8. Security bars that are visible from the street are discouraged.

Design Guidelines REPAIR AND MAINTENANCE
Appendix B - Repair and Maintenance:
A. Awnings
1. Should be washed periodically and kept in good repair.
2. Hardware should be regularly checked for rust or loose mechanisms.
3. Torn or deteriorated awnings should be replaced.
B. Brick and Masonry
1. Materials original to the building should be preserved.
2. Brick and masonry should not be sandblasted or subjected to any kind
of abrasive cleaning. Do not clean with high-pressure water, which
exceeds 450 pounds per square inch. These processes damage brick
surfaces and erode mortar joints.
Brick damaged by sandblasting (Taken from the Secretary
of the Interior's Standards for Rehabilitation)
3. Brick and Masonry should be cleaned with detergent cleansers or
chemical agents.
4. To avoid needlessly introducing moisture or chemicals into the
building, brick and masonry should be cleaned only when necessary to
remove heavy soiling and to stop deterioration.
5. Paint removal should not be done if the paint is firmly adhered to, and
therefore protecting the masonry surface.
0. Water-repellent coatings should not be added unless masonry repairs
have failed to stop water penetration problems.
7. As a general rule, brick and masonry should not be painted unless in
the case of brick, the brick is extremely mismatched from earlier
alterations or cannot withstand weather. (Stone shall not be painted.)
8. Keep exterior brick clean of mildew, efflorescence and dirt. Also keep
exterior brick clean of vines, ivy, and other plant material.
9. Repointing of historic mortar should be with a mortar, which matches
the original in appearance and composition. The use of Portland
cement is generally not appropriate due to the hardness of the mortar
versus the softness of the brick. Most mortar prior to 1900 was
composed of lime and sand. Mortar with similar content should be
applied on buildings of that era.
10. Repointing should be done with original compounds, if it can be
determined, or with a historic compound such as one part lime and two
City of Coppell B-1 Historic Overlay District
Design Guidelines REPAIR AND MAINTENANCE
parts sand. Original type mortar compounds allow for expansion and
contraction while hard mortar or cement prevents the expansion and
contraction process.
11.Repointing should match original width, depth, color, raking profile,
composition and texture.
12. Most silicone based or waterproof coatings have limited effectiveness
and may actually add to moisture problems by not allowing the brick to
breathe. The use of these products is discouraged.
1 3. Brick and masonry should not be stuccoed.
14. Mortar should be removed by hand tools, not electric power saws, for
repairs. Electric tools can damage older brick.
15. Features that are missing may be replaced where extensive
deterioration requires, if it is accurately duplicated.
16. Repair existing stucco and stucco texture. It is inappropriate to remove
stucco from any originally stuccoed surface or to add stucco as a major
wall material to any building, which did not originally use stucco as the
dominant exterior wall material.
C. Chimneys
1. Chimneys should be regularly checked for cracking, leaning, spalling,
and infestation by birds and insects. The use of chimney caps over
chimneys or flue openings is recommended to keep out moisture.
D. Entrances
1. Doors, transoms, and sidelights should be kept clean and the glass
should be washed.
2. Original locks and hardware should be kept oiled and in good repair. If
original hardware is missing or is deteriorated, the use of reproduction
locks and hardware suitable for the building is recommended.
3. Doors with stained wood finish should be kept varnished and paint
over the wood finish is not recommended.
E. Foundations
1. All water should drain away from a building and should not enter the
foundation.
2. Trees, shrubs and other plants should be kept well away from the
foundation to prevent damage from moisture and root movement.
F. Gutters and Downspouts
1. Keep gutters and downspouts in good repair. Make sure they are
properly connected, are clean of leaves and other debris, and channel
water away from the building. Seal all cracks in downspouts with
silicone caulk or sealants.
2. The use of splash blocks to keep water away from the foundation is
recommended.
3. Gutters and downspouts that are deteriorated should be replaced with
new gutters and downspouts. Half-round gutters and round
downspouts are preferable to corrugated designs.
G. Porches & Exterior Ornamentation
1. Use pressure treated wood for exterior repairs and replacement.
City of Coppell B-2 Historic Overlay District
Design Guidelines REPAIR AND MAINTENANCE
2. Keep all porch and trim elements painted.
H. Roof, Cornices
1. Check the roof regularly for leaks, deterioration of flashing, and worn
roof surfaces such as roiled asphalt shingles. An inspection of the
upper floor or attic space during or following a rainstorm can also
assist in detection of water related problems.
2. Know what metals are used in cornice or roof's flashing and use only
similar metals during replacement or repair. Different metals should not
touch each other or a galvanic reaction may occur leading to corrosion.
3. Metal roofs and cornices should be kept painted to prevent rust and
deterioration. Appropriate paints include those with an iron oxide oil
base. Asphalt based paints and aluminum paints should not be use on
historic metals as they could accelerate the rusting process.
I. Siding --
1. Siding original to the building should be repaired and maintained.
Replacement is permitted only when necessary due to deterioration.
Limited clapboard replacement (Taken from the Secretary
of the Interior's Standards for Rehabilitation)
2. Where exterior siding has to be replaced, the use of pressure treated
wood is recommended to prevent deterioration. Replacement siding
should match the profile of the existing siding.
3. When original flashing materials are replaced, the new siding should
match the original as closely as possible, especially with respect to
board size. Original corner boards should be duplicated to their full
original width.
4. Repairs for wood siding such as cracks can be made through the use
of waterproof glue or plastic wood. Large cracks may be filled with
caulk followed by putty or plastic wood. The surface should then be
sanded, allowed to dry, and painted.
City of Coppell B-3 Historic Overlay Distriot
Design Guidelines REPAIR AND MAINTENANCE
5. Oil based paints are recommended for exterior siding.
6. Prevent water from making contact with exterior wood siding. Of
particular importance is keeping all gutters and downspouts in good
repair to keep water from infiltrating the wood-surface.
7. Siding of artificial or substitute materials such as steel, vinyl or
aluminum is discouraged unless 'the board width, corner boards,
cornice and window trim are of the same proportion as the original. If
artificial siding is used, retention of original wood window trim, rafter
tails, and ornamental wood detailing is encouraged
8. Application of such uncharacteristic material as steel siding, aluminum
siding, vinyl siding, imitation stucco, and metal frame windows
obscures the original character of the building and of the
neighborhood. This should be avoided.
Note: The application of synthetic wall material such as aluminum and
vinyl siding has long been discouraged by preservationists due to the fact
that the placement of these materials may seal the wall and cause the
wood to rot. In many cases, existing rotted wood is not removed and the
structural integrity of the house is at risk due to unseen progressive decay.
Seiling altered by vinyl siding (Taken from the Secretary
of the Interior's Standards for Rehabilitation)
J. Signs
1. Abandoned signs and sign hardware should be removed from a
building, unless historic.
2. Signs should be kept painted and mounting bolts should be checked
periodically to make sure they are secure.
3. Light fixtures, conduits, and wiring for signs should be inspected and
replaced when necessary.
City of Coppell B-4 Historic Overlay District
Design Guidelines REPAIR AND MAINTENANCE
K. Windows
1. Windows should be kept clean and free of dirt and grime. Wood sash
surfaces should be painted regularly.
2. Windows should be kept caulked and sealed to aid in energy
conservation.
3. Shutters should be kept painted and in good repair.
4. Old or deteriorated curtains or shades behind house windows should
be removed or replaced.
L. Wood
1. Wood and wood details original to a building should be repaired rather
than replaced.
2. Exposed structural elements such as beams and rafter rails should be
retained and maintained.
3. Replacement of wood features and details should match the original in-
dimension, size and profile.
4. Wood should always be treated and kept in good order (including
paint, stain, nailing, etc.).
