[Ord. No. 5814 §8a.1, 4-27-2004]
The general intent of these standards is to ensure that future
redevelopment and infill development within Clayshire's multi-family
zone is sensitive to and compatible with adjacent single-family uses
and the established character of the neighborhood.
[Ord. No. 5814 §8a.2, 4-27-2004]
The Clayshire Subdivision ("R-4") Urban Design Zoning District
is bounded by I-170 on the east, the alley between Roxburgh and Halifax
on the north, the westernmost properties of Sudbury on the west and
by the southernmost property lines of residentially zoned properties
north of Clayton Road, limited to those properties zoned "R-4", as
depicted below.
 |
[Ord. No. 5814 §8a.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 §8a.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 §8a.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 Clayshire ("R-4"), the
setback provides a soft, landscaped buffer between the building 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 driveway approaches and narrow walkways as traditionally
found in the neighborhood.
 | |
|---|---|
|
|
The open character of the front yard should be maintained.
|
1.
No more than forty percent (40%) of the required front yard setback
shall be covered by impervious material.
2.
Turnarounds or circular drives shall be prohibited within the front
setback.
3.
Shared access points to garages located within the same building,
on the same lot shall be utilized to the maximum extent feasible.
[Ord. No. 5814 §8a.6, 4-27-2004]
A.
The
presence of open areas between and among the multi-family homes in
Clayshire ("R-4") is a strong character-defining feature of the neighborhood.
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.
[Ord. No. 5814 §8a.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.
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 §8a.8, 4-27-2004; Ord. No. 6430 §1, 6-14-2016]
A.
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.
 | |
|---|---|
|
Large canopy trees should be protected during development.
|
[Ord. No. 5814 §8a.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) foot 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 §8a.10, 4-27-2004]
A.
The
following regulation(s) and standard(s) shall govern:
1.
The front yard setback shall not exceed the average of those found
along the block face.
2.
Designated outdoor parking spaces shall not be provided within the
front setback.
3.
Open, covered porches or terraces shall not project into the required
front setback more than five (5) feet.
 | |
|---|---|
|
|
The front yard setback shall not exceed the average
of those found along the block face.
|
[Ord. No. 5814 §8a.11, 4-27-2004]
A.
Due
in part to the relatively low density of existing multi-family housing,
little off-street parking is currently provided in Clayshire ("R-4").
Where it is provided, garage entrances are located to the side or
rear of the structure, creating little visual impact from the street.
In other Clayton neighborhoods, redevelopment has brought with it
the introduction of below-grade front garages. In many cases, the
below-grade garage and associated driveway replace the yard and dominate
the street, completely changing the character of the neighborhood.
Garage placement and scale need to be carefully considered on each
redevelopment project to minimize their visibility and impact upon
the street and surrounding development.
1.
At-grade, side-loading garages or detached garages or rear-loading
garages are preferred in all cases and shall be utilized where fifty-one
percent (51%) or more of the homes on the block have them.
|
|
 |
|---|---|
|
|
Garage entrances shall be located to the rear or side
of the structure.
|
|
|
The following incentives shall apply:
|
2.
Below-grade, front-loading garages shall not be permitted. The following
incentives and standards shall apply for other below-grade or front-loading
garages:
3.
Front-loading, at-grade garages shall not exceed twenty-four (24)
feet in width or fifty percent (50%) of the total length of the home's
front facade, whichever is less.
4.
Third (3rd) garage doors on front facade shall be prohibited. Third
(3rd) or fourth (4th) garage stalls shall be provided in the form
of a separate two-car, detached garage located at the rear of the
lot or as a side entry condition.
5.
For larger, multi-unit structures, shared driveway access to a parking
garage serving a single building is strongly encouraged. The following
incentives shall apply:
a.
A parking garage serving multiple units in a single building with
a shared driveway access shall warrant up to an additional ten percent
(10%) lot area coverage.
[Ord. No. 5814 §8a.12, 4-27-2004]
A.
As
with many Clayton neighborhoods, Clayshire ("R-4") has been dominated
by the use of masonry building materials. Standard size brick in shades
of red and buff are the primary materials found, while accent materials
are limited to contrasting brick, stone or lap siding. Infill development
should utilize appropriate materials with similar characteristics
to help maintain the original character of the neighborhood and ensure
that new development is compatible with the surrounding single-family
neighborhood.
1.
Appropriate primary materials shall be limited to earth-toned brick
as traditionally found within the neighborhood. The use of stucco
and EIFS as primary materials shall be prohibited. Brick may be painted
when compatible with the existing neighborhood.
 | |
|---|---|
|
|
Appropriate primary materials shall be limited to earth-toned
brick as traditionally found within the neighborhood.
|
2.
The number of different materials used on a wall surface shall be
limited to brick and one (1) accent material. The following materials
shall be permitted as accent materials not to exceed twenty-five percent
(25%) of any wall elevation:
4.
A brick ledge or stepped foundation shall be provided to allow no
more than twelve (12) inches of exposed concrete.
5.
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:
7.
Metal shall not be used as a primary roof material.
[Ord. No. 5814 §8a.13, 4-27-2004]
A.
Existing
multi-family development in Clayshire is visually compatible with
surrounding single-family homes due to its modest scale-two (2) stories
in height with relatively low lot coverage. The mass and height of
infill development needs to be carefully considered where single-story
homes are adjoining to ensure compatibility.
1.
Multi-family structures taller than two (2) stories shall provide
a gradual height transition by "stepping-down" to meet the approximate
height of adjacent single-family homes or other structures of a lesser
height.
 | |
|---|---|
|
|
Multi-family structures should "step-down" in height
to provide a more gradual transition to adjacent single-family uses.
|
2.
The maximum building height shall be three (3) stories or forty-five
(45) feet above the average existing grade of the site, whichever
is less. To reduce overall building mass, partial stories above the
third (3rd) story shall not be permitted.
 | |
|---|---|
|
|
To reduce overall building mass, partial stories above
the 3rd story shall not be permitted.
|
3.
Large wall expanses shall be articulated through the use of bays,
insets or stoops related to entrances and windows.
4.
Replication of the design of more than four (4) attached town home
units in any single row shall be prohibited.
5.
The facades of townhouses shall be punctuated by a change in texture
or material, offset or other architectural feature to differentiate
individual units.
[Ord. No. 6509, 11-28-2017]
6.
Building facades (with street frontage) fifty (50) feet or greater
in length shall incorporate wall offsets, a minimum of three (3) feet
in depth, a minimum of every thirty-five (35) feet. To the maximum
extent feasible, significant mass or square footage being added to
an existing home shall be concentrated towards the rear of the lot
to help maintain the character of the street.
 | |
|---|---|
|
|
Buildings 50 feet or greater in length shall incorporate
wall offsets, a minimum of 3 feet in depth, a minimum of every 35
feet.
|
[Ord. No. 5814 §8a.14, 4-27-2004]
A.
The
simple architectural designs currently found within Clayshire ("R-4")
provide a variety of basic design elements that have and should continue
to be incorporated into new development. These elements include gently
pitched roof lines, simple architectural detailing such as stone or
lap siding, dormer windows in upper stories and well-defined front
entries.
1.
Flat, mansard or exotic roof forms not characteristic of the neighborhood
shall be prohibited.
2.
Exposed concrete foundation shall not be permitted where visible
from the street.
3.
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.
