A. 
Intent And Purpose.
1. 
The purpose of the Planned Development District is to provide a means of achieving greater flexibility in residential and commercial development of land in a manner not possible in conventional zones; to encourage a more imaginative and innovative design of projects; to promote a more desirable community environment; and to retain maximum control over both the structure and future operation of the development.
2. 
The Board of Aldermen, upon receiving recommendations of the Planning and Zoning Commission, may by ordinance authorize a Planned Development District when the proposed development, redevelopment or use of a specific tract of land or area warrants greater flexibility, control and density than is afforded under the general regulations of standard zoning districts. These planned development regulations are not intended to allow excessive densities or the development of incompatible land uses, either within the development or as the development relates to the general neighborhood. The standards contained in the following provisions and the related planned development ordinance must be strictly adhered to by the applicant.
3. 
The City may, upon proper application, approve a planned development for a site of at least one (1) acre to facilitate the use of flexible techniques of land development and site design, by providing relief from zoning requirements designed for conventional developments in order to obtain three (3) or more of the following objectives:
a. 
Environmental design in the development of land that is of a higher quality than is possible under the regulations otherwise applicable to the property.
b. 
Promotion of a creative approach to the use of land and related physical facilities resulting in better design and development, including aesthetic amenities.
c. 
Combination and coordination of architectural styles, building forms and building relationships covering different phases within a single development project.
d. 
Diversification in the uses permitted and variation in the relationship of uses, structures, open space and height of structures in developments intended as cohesive, unified projects.
e. 
Use of design, landscape or architectural features to create a pleasing environment.
f. 
Inclusion of special features.
g. 
Functional and beneficial uses of open space areas.
h. 
Preservation of natural features of a development site.
i. 
Creation of a safe and desirable living environment for residential areas characterized by a unified building and site development program.
j. 
Elimination of deteriorated structures or incompatible uses through redevelopment or rehabilitation.
k. 
Rational and economic development in relation to public services.
l. 
Efficient and effective traffic circulation, both within and adjacent to the development site.
m. 
Facilitate implementation of the recommendations of the Comprehensive Plan, where applicable.
B. 
Public Benefit. In exchange for waivers of certain requirements of the Frontenac Zoning Regulations, public benefit shall be provided as determined by the Planning and Zoning Commission and Board of Aldermen. The public benefits to the City that are intended to be derived from the approval of planned developments may include, but are not limited to:
1. 
Use of large tracts of land in a manner which provides a cohesive phased development and minimizes construction impact;
2. 
Extraordinary landscaping and green space provisions;
3. 
Garage entryways by virtue of their location, materials and design that blend with the architecture of the surrounding neighborhood;
4. 
Architectural distinction and significance that would make the development noteworthy;
5. 
Extensive use of high-quality building materials that would add significant value to the property and benefit adjacent properties;
6. 
Special design features such as fountains and other water features, statues, walking paths and landscaped parkway entrances.
7. 
Inclusion of street level landscape gardens, plazas or parks available for public use.
8. 
Public art.
9. 
Provision of new public infrastructure, including, but not limited to, streets, curbs, sidewalks, sanitary sewers, stormwater sewers, lighting and public parking.
C. 
Relationship Of Planned Development Districts To The Zoning Map.
1. 
A mapped district. The "PD" designation is not intended to be attached to existing use districts as an overlay but is a distinct mapped zoning district.
2. 
Plan approval required. Although the "PD" designation may be applied to parcels of land as a mapped zoning district, it is the intent of this Chapter that no development or redevelopment of the property encompassed by the "PD" designation take place until an acceptable development plan has been reviewed and approved in conformance with the requirements of this Section. Any preexisting uses within the area encompassed by the "PD" designation shall have the status of non-conforming uses, as outlined in Section 405.130, until such time as they are included in an approved development plan.
3. 
Types of planned developments. All areas of the City subject to the "PD" designation shall be assigned one (1) of the following subclassifications which shall be considered a separate zoning district and subject to the specific restrictions and limitations outlined in this Section:
a. 
Planned Development — Residential ("PDR"): Planned developments involving residential uses only.
b. 
Planned Development — Retail/Commercial ("PDC"): Planned developments involving retail/commercial uses only.
c. 
Planned Development — Mixed Use ("PDMXD"): Planned developments Involving a mixture of residential and non-residential uses.
4. 
These subclassifications may be designated by the City at the time of the original zoning of the parcel in question, or the City may make the designation at the time of development/redevelopment plan application. In the instance of a request for Zoning Map amendment, the applicant shall request a specific subclassification; however, it shall be at the discretion of the City, in light of the recommendations of the City's Comprehensive Plan as well as the surrounding neighborhood, to grant the requested subclassification or require a more restrictive one.
D. 
Permitted Uses. Approval of permitted uses within a PD district is subject to considerations as stated in the intent and purpose of the PD regulations. The listing of permitted uses within each "PD" subclassification shall be as follows:
1. 
Planned Development Residential, PDR.
a. 
Single-family detached.
b. 
Single-family attached (villas or townhomes).
c.

Building Height — General Conditions.
a) 
In order to accommodate the overland flow path requirement of the Metropolitan Sewer District of St. Louis (MSD), overall building heights may be increased by a maximum distance of the difference between the site grade and calculated base flood elevation (BFE), plus three (3) feet, according to the following definitions and example:
1) 
Overland Flow Path Requirement. The MSD overland flow path requirement mandates that an above-ground, natural floodway be maintained through the site to account for stormwater runoff that exceeds the capacity of the existing storm sewer(s) that serve the site, based on a 100-year (1% probability), 20-minute rainfall event (design condition rainfall event).
2) 
Base Flood Elevation. Based upon site topography, impervious surface coverage, storm sewer capacity, and other factors, the depth and extent of above-ground water generated by the design condition rainfall event will result in a specific water elevation, referred to as the "base flood elevation" (BFE).
3) 
In areas where a BFE is present due to overland flow requirements, building heights may be increased as illustrated in the following example for Height Zone 2:
I. 
Height Zone 2: Maximum building height = 645 feet MSL.
II. 
Example site elevation = 571 feet MSL.
III. 
Example overland flow path BFE = 575 feet MSL (4 feet above grade difference).
IV. 
Allowable building height increase: 4 feet + 3 feet = 7 feet; 645 feet MSL + 7 feet = 652 feet MSL allowable increased maximum building height.
b) 
For pitched roofs, gabled roofs, and hipped roofs, building height shall be measured to the mean distance between the roof eave line and the roof peak.
c) 
Building parapet walls may extend up to six (6) feet above the maximum building height.
d) 
Architectural features, including features related to occupiable roofs, may extend up to twelve (12) feet above the maximum building height, subject to the requirements of Section 405.095(D)(1)(a)(iv).
h.

D. 
"BD" Business District Architectural Design Standards.
1. 
Building Articulation.
a. 
Building Facades.
i. 
Building composition should clearly define and articulate the building's different purposes, using building elements, treatments, and architectural expression to define the various pieces that make up the larger building.
a) 
Clearly differentiate the divisions between ground floor, middle floors, and roof forms (i.e., base, middle, and cap design hierarchy). [O]
b) 
Establish a sense of scale in the design of larger buildings through vertical and horizontal articulation and material differentiation. [P]
ii. 
The maximum total length for any facade shall be three hundred (300) feet.
iii. 
Facades longer than seventy (70) feet shall be divided into smaller segments or "apparent faces" with variation to building setbacks, recesses, and projections above the ground floor. The apparent face is the length of a facade plane that is unbroken by vertical changes in depth. Limiting this length reduces the perceived bulk of a long building facade.
a) 
Buildings with facades over seventy (70) feet wide must incorporate wall projections or recesses, or changes in wall plane for two (2) feet minimum depth, at least every seventy (70) feet. [Q]
b) 
Vary the skyline of the facade by at least one (1) story not including towers, and/or include upper floor setbacks. [R]
1) 
A minimum of thirty percent (30%) of the length of the skyline shall be varied by at least one (1) story.
iv. 
Flat roofs and hidden pitched roofs require a parapet on all facades facing public streets and primary internal circulation streets.
v. 
The roofline of a building shall not run in a continuous plane for more than seventy (70) feet without changes in elevation. The roofline must be broken up by providing articulations in the facade of the building; changes in the height of the roof; architectural features such as corner towers, turrets, rooftop pergolas, rooftop loggias, etc.; and/or changes in color, material, forms, etc., subject to the following conditions: [S]
a) 
Up to thirty percent (30%) of the roofline may extend up to twelve (12) feet above the maximum building height, as specified in Section 405.095(C)(3)(f).
b) 
Rooftop pergolas, rooftop loggias, rooftop penthouses, and other architectural features may extend up to twelve (12) feet above the maximum building height, as specified in Section 405.095(C)(3)(f), subject to the following conditions:
1) 
The architectural feature(s) shall be set back a minimum of twenty (20) feet from the roof edge; and
2) 
The architectural feature(s) shall comprise not more than forty percent (40%) of the total roof area.
vi. 
Design the building to reduce real and perceived building mass including using the methods of mass variation and facade articulation. Ideally combine both methods in building design.
vii. 
Mass variation methods reduce actual building mass and scale while meeting the development standards for building height. This method modulates a building floor or wall in a manner that creates a physical relief horizontally or vertically in the building mass and architectural form.
viii. 
Facade articulation methods reduce perceived building mass by providing human scale components and expressing horizontal and vertical scale. These methods include accent lines, color and material changes, and minor wall offsets. [T]
a) 
Utilize minor wall offsets of up to two (2) feet.
ix. 
Upper floors should be distinguished from the building base. Use varied geometry in upper floors and modulate and articulate facade to reduce perceived building bulk. [U]
a) 
Step-back upper floors to reduce visual impact at the pedestrian scale, also permitting balconies in the step-back.
x. 
Nearly vertical roofs (A-frames) and piecemeal mansard roofs (used on a portion of the building perimeter only) are prohibited.
b. 
Block Corner Articulation.
i. 
Provide signature design elements at district gateways and on prominent corners or intersections as landmarks.
ii. 
Establish block corners with architectural articulation that relates to street activating uses.
iii. 
The full height of tall buildings may be expressed at corners to provide variation and increased vertically on buildings with tower step-backs or buildings may be chamfered or set back in plan to create additional sidewalk space or outdoor program space.
c. 
Building Base Articulation.
i. 
Vary base height up to the maximum height and/or between the retail use and upper floors.
ii. 
Encourage two-story retail spaces. This variation should respond to the street character and typical widths, heights, and modulation of existing buildings to create a contextually sensitive and human scaled outdoor room.
iii. 
Design the base of the building to be sufficiently flexible to accommodate a variety of store design options for future retail tenants to use in expressing their brand identities.
a) 
A variety of storefront widths, depths, heights and transparency treatments should be possible so that the needs of different retail tenants can be met.
b) 
Use the architectural framework to create a rhythm of glazing, entrances, and display areas.
iv. 
Utilize variations such as slight projections, setbacks, and canopies between different storefronts. Users should be able to easily identify the number of retailers in a building from a distance.
v. 
Utilize horizontal architectural details such as cornices, continuous balconies, frames, projections, and step-backs to differentiate the retail floor(s) from upper floors.
vi. 
Utilize plane changes that create significant vertical and horizontal breaks, and shadow lines on the facade. Architectural projections as small as twelve (12) inches can be effective.
vii. 
Avoid overly long, continuous forms of weather protection along the full building facade. This diminishes the visibility of individual storefronts.
viii. 
Consider variation in building materials or color to add texture to lower floors most visible to those at pedestrian level.
2. 
Architectural Elements And Features.
a. 
Ground Floor Windows And Doors.
i. 
A minimum of seventy five percent (75%) of the total area of ground floor facades facing a public street or primary internal circulation street shall be made of glass or other transparent materials with a minimum fifty percent (50%) transmittance factor and a reflectance factor not greater than 0.25, or otherwise designed to allow pedestrians to view activities inside the buildings.
ii. 
In order to support an active street level appropriate to a business district, a minimum of one (1) entrance door shall be provided at a minimum interval of thirty (30) feet for the entire length of all ground floor facades facing a public street or primary internal circulation street.
b. 
Upper Floor Windows And Doors.
i. 
Upper floors should incorporate traditional vertically proportioned window and door openings with less window glazing and transparency than the lower floors.
ii. 
Windows shall be provided on all building facades in a manner and proportion that positively contributes to the overall architectural style and design of the building.
iii. 
All-glass facades are prohibited; maximum allowable glazing on any single facade shall be fifty percent (50%) of the total facade area.
c. 
Balconies. Balconies are encouraged on street facades, but not required. A maximum of forty percent (40%) of the total facade area may be covered with balconies. False balconies are prohibited, and balcony support structures must be integrated with building facade.
d. 
Building Signage. Building signage shall be an integral part of the overall building design. Signs shall not obscure important architectural details. Principal sign types appropriate for the district include:
i. 
Wall Signs. Positioned within architectural features and aligned with others on a block to maintain established patterns;
ii. 
Projecting Signs. Positioned along the first-floor level of the facade may take on their own special shape or create their own symbol within the overall facade design; and
iii. 
Awning Signs. Positioned to emphasize special shapes or details of the facade, to draw attention to shop entrances or to emphasize a display window. Internally lit signs are discouraged. Where there is sufficient ambient light avoid signage lighting. Illuminated wayfinding signage is appropriate (i.e., structured parking entrances).
e. 
Building Equipment. Building equipment shall be located to minimize visual impact. Mechanical equipment should be located within the building when possible. Rooftop equipment should be incorporated into roof design and set back from frontage facade to limit visibility. All building equipment shall be screened from any public vista view. Mechanical appurtenances shall not be located on primary facades.
f. 
Screening. Screens and screening should be used to hide from public view elements that negatively impact and detract from the design of a building. Screening form, material, and color shall be consistent with the building design, colors, and materials. Screening should not increase the height of the building, and the height of any screen shall be the minimum required to adequately conceal its intended element.
g. 
Night Lighting. Night lighting on the exterior of the building shall be designed for architectural, aesthetic, or decorative purposes. Low lighting levels should be used to create pleasing pedestrian spaces (i.e., string lighting over an outdoor dining area). Ambient light should come from streetlights, building facade lighting, and storefronts. Security lighting should be designed for safety, as well as night-time appearance.
3. 
Building Materials.
a. 
Building Materials — General Requirements.
i. 
High-Quality Materials. High-quality, well-tested, durable, weather-resistant, exterior grade, and preferably natural materials shall encompass the majority of finished surfaces.
