[Ord. No. 5814 §10a.1, 4-27-2004]
The general intent of these standards is to ensure that renovation
and redevelopment responds to and protects the established character
of the Westwood Corridor. Renovation standards shall apply only to
structures constructed prior to 1940.
[Ord. No. 5814 §10a.2, 4-27-2004]
The Westwood Corridor ("R-6") Urban Design Zoning District is
bounded by Wydown Boulevard on the north and Clayton Road on the south,
limited to those properties zoned "R-6", as depicted below:
 |
[Ord. No. 5814 §10a.3, 4-27-2004]
The regulations of this urban design zoning district shall supersede
or supplement, as applicable, the regulations of the base zoning district.
Where conflict results between the regulations of the urban design
zoning district and the provisions of the base zoning district, the
provisions of the urban design zoning district shall control.
[Ord. No. 5814 §10a.4, 4-27-2004]
The uses permitted by right and by conditional use permit are
listed in the Table of Permitted Uses found in the base zoning district.
If a "P" (permitted by right) or a "C" (permitted by conditional use
permit) is not indicated for a use in the base zoning district or
a use is not included in the base zoning district, it is prohibited.
[Ord. No. 5814 §10a.5, 4-27-2004]
A.
The
high visibility of the front setback from the street creates a significant
impact on a neighborhood's character. In the Westwood Corridor, the
setback and open courtyards provided by the many U-shaped buildings
provides a soft, landscaped buffer between the building and the street.
New structures and renovations should generally reflect the configuration
of the structure being removed to maintain the established character
of the street.
B.
New Construction—Design Standards.
1.
A new structure replacing a U-shaped or other courtyard-oriented
structure shall be designed in a similar configuration to maintain
an open appearance at the street.
 | |
|---|---|
|
|
When replacing a courtyard-oriented structure, a new
structure should be designed in a similar configuration to maintain
an open character at the street.
|
2.
Underground parking structures shall be accessed by a single drive,
as typically found in the corridor, to the maximum extent feasible.
[Ord. No. 5814 §10a.6, 4-27-2004]
A.
The
Westwood Corridor is home to a variety of lot sizes and configurations.
Many of the lots offer limited opportunities for flexibility in coverage
due to their smaller size and proximity to adjacent homes. However,
a small number of lots along the southwest side of Westwood are significantly
deeper and wider, creating the potential for additional coverage towards
the rear of the lot without creating negative visual impacts.
B.
No more than fifty percent (50%) of the total lot shall be covered by impervious material. Structures providing a front courtyard or increased front yard setback, as specified in Section 410.585 Rear Yard Setbacks, shall not be bound to a maximum total lot coverage, provided that required front and side yard setbacks are met.
[Ord. No. 5814 §10a.7, 4-27-2004]
A.
Building
entrances in the corridor have typically been oriented towards the
front yard or courtyard and the street, accenting the primary facade
of the building. Although the physical layout of the structures vary
from a "U" shaped design opening to a courtyard, to a more uniform,
rectangular shape, the repetition of the entries help form a uniform
line along the street. New structures should be designed to be consistent
with the typical organization of the neighborhood.
 | |
|---|---|
|
Main entrances should be oriented towards the street,
as typically found in the Corridor.
|
B.
The
front entrance to a building shall be located on the front facade
of the building oriented towards the front yard or courtyard and street,
as found typically in the corridor.
[Ord. No. 5814 §10a.8, 4-27-2004; Ord. No. 6430 §1, 6-14-2016]
The shady canopy provided by mature trees is an important character-defining feature in many of Clayton's older residential neighborhoods. This is particularly true in the Clayton Gardens and Clayshire where large, evenly spaced trees line the street, buffering homes from traffic and giving the neighborhood a more intimate feeling for pedestrians and residents. Also contributing to this character are the many additional large caliper trees scattered among the homes. As larger homes are introduced, they should be sensitive to this character, preserving trees and vegetation. Specific requirements are set forth in Article XXX: Trees and Landscaping Regulations.

[Ord. No. 5814 §10a.9, 4-27-2004]
A.
The
wooded, gently rolling topography typical of the St. Louis area contributes
to the visual interest and variety of Clayton's residential neighborhoods.
Disturbing existing site topography to accommodate larger homes with
walk-out basements or below-grade garages can lead to significant
drainage problems, particularly for adjacent properties. New homes
should minimize site disturbances and should mitigate runoff.
1.
To the maximum extent feasible, development shall follow and respect
the existing topography of the site.
2.
Extensive grading or unusual site improvements (e.g., retaining walls
greater than four (4) feet in height) shall not be permitted, unless
deemed compatible with the neighborhood and approved by the Plan Commission.
3.
Site drainage patterns shall be designed to prevent concentrated
surface drainage from collecting on and flowing across adjacent lots,
pedestrian paths, walks and sidewalks. Stormwater drainage shall be
connected to a storm sewer where available as determined by the City.
[Ord. No. 5814 §10a.10, 4-27-2004]
A.
The
consistent appearance of a broad, landscaped front setback and uniform
building edge creates a sense of visual continuity along the street
and creates an open appearance characteristic of the neighborhood.
As redevelopment occurs, the open character of the front setback should
be preserved.
B.
The
front yard setback shall not be less than the average of those found
along a block face.
[Ord. No. 5814 §10a.11, 4-27-2004]
A.
The
deep lot configurations found in the southwest area of the corridor
provide an opportunity for new development to utilize the rear yard
setback to acquire additional buildable area and density without negatively
impacting adjacent development. Actual appropriate setbacks will vary
slightly in order to accommodate services, such as trash receptacles,
and will be evaluated during the site plan review process.
B.
The
minimum rear yard setback shall be fifteen (15) feet from the rear
property line to the closest rear wall of the principal structure.
The following incentives shall apply:
1.
Structures designed in a U-shaped form that provide a front courtyard
space open to and visible from the street shall not be required to
have a minimum rear yard setback. The total area of a front courtyard
shall not be less than twenty percent (20%) of the total building
living area.
2.
Structures shall be permitted to increase their allowable front yard
setback by fifteen (15) feet in lieu of providing a rear setback.
[Ord. No. 5814 §10a.12, 4-27-2004]
A.
One
(1) of the many appealing features of the Westwood Corridor is its
thoughtful treatment of off-street parking. Most of the structures
provide underground, off-street parking that is visually and functionally
integrated with the structure. As a result, broad lawns and shade
trees border most buildings rather than the unsightly, exposed parking
lots typically found with many more modern multi-family developments.
New development should provide off-street parking that is compatible
with the established character of the neighborhood.
 |
1.
Off-street parking shall be accommodated below ground and be structurally
and visually integrated as part of the primary structure through the
use of similar materials and architectural detailing.

A.
As
with many Clayton neighborhoods, the Westwood Corridor has traditionally
been dominated by the use of masonry building materials. Standard
size brick in predominantly red tones is the primary material found.
Accent materials are more varied, with a several varieties of stone
found on many structures at the foundation or around windows and doors.
Stucco is present as an accent material, but is currently limited
to few English Tudor style structures. Care should be taken to preserve
original building materials and to ensure that new or replacement
materials are of a similar appearance and character as those traditionally
found within the corridor.

materials used to enhance the simple design of many Corridor structures.

B.
New Construction—Design Standards.
1.
Appropriate primary materials shall be limited to masonry materials,
such as brick or a combination of brick and stone, as traditionally
found within the corridor. Brick may be painted when compatible with
the existing neighborhood.
2.
Stucco shall be permitted as an accent material not to exceed twenty-five
percent (25%) of any wall elevation.
3.
Retaining walls shall be constructed from masonry materials similar
to those used on the primary structure.
4.
Visible roof materials shall be of a similar scale and texture to
those traditionally used.
6.
Metal shall not be used as a primary roof material.
C.
Renovation—Design Standards.
1.
Character defining features, such as stone retaining walls, steps
and foundations, shall be preserved to the maximum extent feasible.
2.
Enclosure of or other significant alterations to decks or balconies
that were not originally enclosed shall be prohibited.
3.
Original masonry building materials shall not be altered or otherwise
covered with new building materials, such as stucco or vinyl siding,
or painted.
4.
Replacement materials on visible roof surfaces shall be of a similar
scale and texture as those traditionally used, such as tile or slate.

[Ord. No. 5814 §10a.14, 4-27-2004]
A.
Building
heights in the corridor are currently fairly uniform, ranging from
two (2) to three and one-half (3½) stories tall with fairly
blocky rectangular or "U" shaped configurations oriented towards the
street or a center lawn or courtyard. Surrounding development ranges
from blocky, mid-rise development along Hanley to a range of two-
to three-story single- and multi-family dwellings in the Mooreland's
neighborhood to the east. The height and mass of new development should
respond to both surrounding development and adjacent development within
the corridor. Subtle articulation of the wall surface with design
elements such as a soldier course, stone lintels or sills or brick
row-lock are common details in the neighborhood.
1.
Building height shall not exceed three (3) stories or forty-five
(45) feet above the average existing grade of the site. Exceptions
to the maximum height shall be permitted on lots west of Westwood
Drive and south of Buckingham, building heights shall not exceed three
(3) stories or forty-five (45) feet above the average grade of the
site within twenty (20) feet of the front setback. Beyond twenty (20)
feet from the setback, building heights may "step-up" to a maximum
of five (5) stories or sixty-five (65) feet.
 | |
|---|---|
|
South of Buckingham, building heights may "step-up"
from 3 stories or 45 feet to a maximum of 5 stories or 65 feet beyond
20 feet from the front setback.
|
2.
Articulation of the wall surface shall be required. This may be accomplished
by a change in the brick pattern or the addition of stone detailing.
[Ord. No. 5814 §10a.15, 4-27-2004]
A.
Though
fairly simple in their overall form, generally rectangular or "U"
shaped with gently pitched roof lines or pediment walls, the structures
found in the Westwood Corridor have many subtle architectural details
that add to their character. A wide variety of decorative windows
add visual interest. They range from groupings of multi-paned windows
or double-hung windows to some more ornate accent windows, such as
leaded or stained glass. Stone sills, headers or casings further enhance
many of the windows. Also significant are the many well-defined entryways.
Typically above the grade of the sidewalk, many have elegant curving
staircases, ornamental railing or stone retaining walls leading to
the entrance. In order to protect the rich character of the corridor,
care should be taken to preserve traditional architectural detailing
during significant renovation projects and ensure that infill development
utilizes window, roof line and entryway design and placement that
complements this established character.

1.
Windows shall be of a similar size, shape and architectural character
to those traditionally found in the corridor.
2.
Roof forms and treatments shall be similar to those found on existing
structures in the corridor. Flat roof lines shall be concealed by
a parapet wall or other decorative feature as found in the corridor.
3.
New structures shall have a solid-to-void (wall-to-window) ratio
similar to that found on original structures in the corridor.

to the maximum extent feasible. Alternatively, substitute materials
shall be considered if the dimension, profile and finish closely match
the original.
b.
Snap-in muntins shall be used to create similar light and shadow
patterns, if direct replacement of true divided light windows is not
feasible.
