[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; Ord. No. 6986, 1-27-2026]
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. 
A minimum of sixty percent (60%) of the required front yard setback shall be covered by greenspace.
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; Ord. No. 6986, 1-27-2026]
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.
B. 
A minimum of sixty percent (60%) of the total lot shall be covered by greenspace. Additional lot coverage may be earned through the incentives provided in Section 410.445, Garage Width and Location.
[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; Ord. No. 6986, 1-27-2026]
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.
a. 
An at-grade, side-loading, rear-loading or detached garage condition shall warrant up to a five percent (5%) reduction in required total lot greenspace.
2. 
Below-grade, front-loading garages shall not be permitted.
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, 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 and shall warrant up to a five percent (5%) reduction in required total lot greenspace.
[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:
a. 
Stucco;
b. 
Wood lap siding; or
c. 
Stone or similar product.
3. 
The use of the following materials shall be prohibited:
a. 
EIFS,
b. 
"Jumbo" brick, or
c. 
Split-faced block.
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:
a. 
Wood ties,
b. 
Versa-lok,
c. 
Keystone,
d. 
Windsor, or
e. 
Similar modular block wall systems.
6. 
Asphalt shall not be used for driveways or driveway aprons. These features shall be constructed of one (1) of the following materials:
a. 
Exposed aggregate;
b. 
Brick pavers; or
c. 
Stamped concrete.
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.
