[Ord. No. 5814 §7a.1, 4-27-2004]
The general intent of these standards is to ensure that infill,
redevelopment and renovation within Clayton Gardens and the Clayshire
Subdivision is compatible with the established character and variations
within each neighborhood by utilizing complementary design characteristics,
setbacks, massing and building heights.

A.
The
Clayton Gardens Urban Design Zoning District is bounded by the northern
City limits on the north, the western City limits on the west, Brentwood
Boulevard on the east and the southernmost property lines of residentially
zoned properties north of Maryland Avenue, as depicted below:
 |
B.
The
Clayshire Subdivision Urban Design Zoning District is bounded by I-170
on the east and north, by the western City limits on the west and
by Clayton Road on the south, limited to those properties zoned "R-2"
as depicted below:
 |
[Ord. No. 5814 §7a.3, 4-27-2004]
The regulations of these urban design zoning districts 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 §7a.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.

A.
The
open, park-like appearance of the front setback is a significant character-defining
element. It provides a soft, landscaped buffer between the homes and
the street creating an inviting, unified appearance. Paving and other
hard materials, in excess, can detract from this appearance and should
be limited to the narrow driveways and walkways as traditionally found.
 | |
|---|---|
|
|
The open character of the front setback should be maintained
as redevelopment occurs.
|
1.
Lots zoned "R-2" shall have no more than thirty percent (30%) of
the required front yard setback covered by impervious material; except
that for properties fronting on Anderson Park Court within the Clayshire
subdivision, no more than forty-five percent (45%) of the required
front yard setback shall be covered by impervious material.
[Ord. No. 6700, 5-25-2021]
2.
Lots zoned "R-4" in Clayton Gardens shall have no more than forty
percent (40%) of the required front yard setback covered by impervious
material.
3.
Driveways shall narrow to a maximum of ten (10) feet in width at
the street edge or per the City of Clayton standards.
4.
Turnarounds or circular drives shall not be permitted within front
setback.
[Ord. No. 5814 §7a.6, 4-27-2004; Ord. No. 6068 §1, 4-14-2009]
A.
The
presence of open lawn and landscaped areas throughout Clayton Gardens
and Clayshire is a strong character-defining feature of the neighborhoods.
New development should utilize similar lot coverage as traditionally
found along a block to maintain the open character of the street and
ensure compatibility with adjacent homes.
1.
No more than forty percent (40%) of the total lot may be covered by impervious material. Incentives for additional lot coverage may be earned in Section 410.375, Garage Width and Location; provided however, that lots fronting on Anderson Park Court within the Clayshire subdivision may have no more than fifty-five percent (55%) of the total lot covered by impervious material and that no additional incentives may be earned with respect to those lots.
[Ord. No. 6700, 5-25-2021]
2.
Lots zoned "R-4" in Clayton Gardens shall have no more than fifty-five
percent (55%) of the total lot covered by impervious material. No
additional bonuses may be earned.
[Ord. No. 5814 §7a.7, 4-27-2004]
A.
Building
entrances have typically been oriented towards the front yard and
the street, accenting the primary facade of the building and creating
a uniform line along the street. New structures should be designed
to be consistent with the typical organization of the neighborhood.
B.
For
buildings located on lots zoned "R-2" and lots zoned "R-4" in Clayton
Gardens, the front entrance to a building shall be located on the
front facade of the building oriented towards the front yard and street
as found typically in Clayton's residential neighborhoods.
[Ord. No. 5814 §7a.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 §7a.9, 4-27-2004; Ord. No. 6430 §1, 6-14-2016]
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. Specific requirements are set forth in Article XXX: Trees and Landscaping Regulations.
 |
|---|
|
Alterations to existing site topography should be minimized
to prevent drainage problems.

[Ord. No. 5814 §7a.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.

New homes should respond to the existing character of
the
neighborhood by utilizing similar front setbacks.

A.
General. The garage has not typically been a dominant feature
in Clayton Gardens and Clayshire. Locating the garage to the rear
or side of the home, as is typical in these neighborhoods, allows
the architectural details of the home and front yard to define the
character of the street. Below-grade front garages have been introduced
in several areas of Clayton Gardens. In many cases, the garage and
associated driveway replace the yard and dominate the street, completely
changing its character. To protect the established character of these
neighborhoods, garage placement and scale need to be carefully considered
to minimize visual impacts upon the street and surrounding development.

A.
Clayton
Gardens and Clayshire Subdivision have traditionally been dominated
by the use of masonry building materials. Standard size brick in a
variety of red tones is the primary material found, although the original
brick has been painted in some instances. Accent materials vary and
include: wood lap siding, stone and stucco. Materials and colors utilized
for significant renovations or for new homes should be compatible
with those found in the neighborhood.
1.
The number of different materials used on a wall surface shall be
limited to brick and one (1) accent material. The accent material
shall not exceed twenty-five percent (25%) of any wall elevation.
 | |
|---|---|
|
|
Primary building materials are limited to brick, with
one accent material not to exceed 25% of the total wall coverage.

2.
Brick color shall be compatible with that found on other homes along
the block. Brick may be painted when compatible with the existing
neighborhood.
5.
A brick ledge or stepped foundation shall be provided to allow no
more than twelve (12) inches of exposed concrete.
6.
Retaining walls shall be constructed of materials similar in color,
texture and scale as those used on the primary structure. The following
materials shall not be used for any retaining walls visible from the
street or from the ground level of any adjoining residence:
8.
Metal shall not be used as a primary roof material.

[Ord. No. 5814 §7a.13, 4-27-2004]
A.
As
described in the character analysis, the established character of
development varies on either side of Forsyth. West of Forsyth, homes
have traditionally been one-story ranch designs with a strong horizontal
orientation. Homes and accessory structures built with increased heights
and densities in this area tend to be highly visible in contrast to
the established neighborhood, often dramatically reducing lawn areas
and the traditionally open character of the lots. In contrast, homes
along Gay Avenue and east of Forsyth are more typically two-story
in height, making the integration of new development somewhat easier.
Designs in each area should be responsive to surrounding development,
ensuring that they are compatible in terms of mass, scale and height
with existing homes along a block. Within the limited area of "R-4"
zoning along Gay Avenue in Clayton Gardens, height will be evaluated
for compatibility by the Architectural Review Board at the time of
submittal, unless otherwise noted.
1.
The maximum building height shall be limited to two (2) stories or
thirty (30) feet above the average existing grade of the site, whichever
is less. Partial stories above the second (2nd) story shall be prohibited
to minimize the potential mass of homes.
 | |
|---|---|
|
|
The maximum building height shall be limited to 2 stories
or 30 feet above the average existing grade of the site, whichever
is less.
|
2.
To avoid tall, blocky building forms, new structures and additions
shall incorporate a transition in height and scale through one (1)
of the following techniques:
a.
"Stepping-down" to meet the approximate height of the adjacent structure.
 | |
|---|---|
|
|
Partial stories under sloping roofs are preferred. Tall,
blocky building forms should be avoided.
|
b.
Utilizing dormers and sloping roofs to accommodate upper stories
for major renovations and new construction.
c.
Concentrating significant mass or square footage being added to an
existing home towards the rear of the lot.
d.
Increasing the side yard setback one (1) foot for every five (5)
feet the height of the structure exceeds the height of the adjacent
structure at the side yard.
e.
Utilizing a roof pitch and overhang similar to that of the adjacent
structures.
 | |||
|---|---|---|---|
|
|
Single-family structures should "step-down" to meet
the approximate height of the adjacent structure.
| ||
f.
Installing canopy trees twenty (20) feet on center within the side
yard to help break up the appearance of the taller structure. Trees
must be installed per recommendation by the City's landscape architect.
3.
The height of accessory structures shall be limited to one and one-half
(1½) stories or sixteen (16) feet above the average existing
grade of the site, whichever is less.
[Ord. No. 5814 §7a.14, 4-27-2004]
A.
Architectural
detailing on homes in Clayton Gardens and Clayshire is typically fairly
modest. Homes generally have gently sloped roofs, regardless of their
height, and often incorporate dormers as part of a partial story.
Simple facades are punctuated by a variety of window styles, most
accented with contrasting shutters. The design of infill development
should incorporate elements that complement the character of existing
development along a block.
1.
Flat, mansard and other exotic roof forms not compatible with established
neighborhood character shall not be permitted.

as those found on the block.
4.
Blank walls shall not be visible from the street.
5.
Exposed concrete foundation shall not be visible from the street.
6.
Columns shall be compatible with the predominant architectural style
of the neighborhood. Size, materials and proportions of the columns
to the structure shall be provided on submitted plans.
