A. 
The Maryland Gateway Overlay Zoning District (hereinafter known in this Article as the "MD" Overlay District) applies to properties along the north and south sides of the Maryland Avenue corridor from the western City limits, east, to the centerline of Brentwood Boulevard, which are identified in the 2010 Master Plan Update and Retail Strategy. The area encompassed in the Maryland Gateway Overlay Zoning District is considered a gateway to downtown which gives the opportunity for creating a memorable and representative entry to the core of the City and is adjacent to the heart of commercial and service activities in the City of Clayton. The Maryland Gateway District is intended to maintain a walkable, pedestrian scale, human-focused corridor with changes to the streetscape to reflect the urban character of downtown. Much of this can be built upon the already strong presence of small retail establishments on the north side of the street, which help define the street edge and serve as a transition to adjacent residential areas. The purpose is to create a lower density mixed use district that provides an iconic gateway into downtown Clayton while respecting the northern residential neighborhood and the civic uses to the south. In order to maintain this area as "pedestrian friendly", structures must be human in scale. Building mass, density and frontage variations should create a visually attractive and inviting streetscape within the urban context.
B. 
The purpose of these regulations is to foster appropriate use of existing structures and enable compatible redevelopment, which serves the following goals:
1. 
Support and enhance existing retail development along Maryland Avenue and promote structures that have sidewalk frontage suitable for smaller retail and personal service activities.
2. 
Stimulate designs that minimize scale and mass as perceived from the sidewalk.
3. 
Orient front doors and align buildings to address Maryland Avenue.
4. 
Careful stepping of building height and regulation of uses to ensure that adjacencies are appropriate and not overly abrupt.
5. 
Encourage mixed use development, with ground level commercial retail and upper level residential uses.
6. 
Encourage a built environment that is friendly to the presence of people living, shopping, visiting, enjoying or spending time in the area.
[Ord. No. 6276 §1, 6-25-2013]

[Ord. No. 6276 §1, 6-25-2013]
The regulations of the overlay district shall supersede or supplement, as applicable, the regulations of the base zoning district. Where a conflict exists between the regulations of the overlay districts and the provisions of the base zoning district, the provisions of the overlay district shall control, except for those properties governed by the Special Development Zoning District (SDD), adopted by Ordinance Number 4220, in which case the provisions of that ordinance shall control.
[Ord. No. 6276 §1, 6-25-2013]

All ground floor uses shall be retail or restaurant uses, but may also include beauty salons, dry cleaning facilities and similar personal care services. Financial institutions (banks, savings and loans and credit unions) and other office uses are also permissible. In no case shall retail, restaurant or personal service uses constitute less than fifty percent (50%) of the total ground floor area of a structure, or in the case of a development project with multiple structures, less than fifty percent (50%) of the total gross ground floor area of all structures.
2.

A. 
The maximum building height in the "MD" Overlay District is three (3) stories, not to exceed thirty-five (35) feet for properties in an underlying "C-1" zoning district, and seven (7) stories or ninety (90) feet, whichever is less, for properties in other underlying zoning districts. The maximum building height for properties south of Maryland Avenue may be modified subject to the provisions and requirements of the planned unit development process outlined in Chapter 405.
B. 
For buildings permitted to exceed the maximum height through the planned unit development process, a fifteen (15) foot stepback (upper story building setback) shall be provided beginning at the third (3rd) story level or thirty (30) feet above grade, whichever is less. However, the Plan Commission shall have the authority to require a different stepback(s) for buildings dependent upon building height, lot size, nearby land uses and structures, and other relevant factors. Stepbacks shall be proportional to the amount of building height. The upper story stepback shall be provided along all building elevations with street frontage, excluding alleys.
[Ord. No. 6276 §1, 6-25-2013]
The maximum floor area ratio (FAR) is three (3.0). The maximum floor areas may be modified subject to the provisions and requirements of the planned unit development process outlined in Chapter 405.

A. 
The following are setback/stepback requirements in the Maryland Gateway Overlay Zoning District:
1. 
Front yard. There is no minimum front yard setback requirement in the Maryland Gateway Overlay District. All property lines which abut a street are considered frontages. Building up to the front property line is encouraged.
2. 
Rear yard. The required rear yard setback in the Maryland Gateway Overlay District is a minimum of fifteen (15) feet. Modifications to the required rear yard setback are permitted/required under the following conditions:
a. 
Where a corner lot exists, the property line opposite to the front yard line with the greater street frontage shall be considered the side yard and the property line opposite to the front yard line with the lesser street frontage shall be considered the rear yard.
b. 
Where a property has three (3) or more street frontages, that portion of the property opposite the frontage on the street designed or classified for the highest traffic volume shall be considered the rear yard.
c. 
An accessory building not exceeding twenty (20) feet in height may occupy up to thirty percent (30%) of the area of a required rear yard. Accessory buildings may be attached to the principal building or not less than ten (10) feet from the principal building. In all cases, no accessory building shall be closer than five (5) feet to any rear property line or to any property line that abuts a residential zoning district, nor shall they be located along any street frontage.
3. 
Side yard setbacks.
a. 
The side yard setback requirements are zero (0), except where a lot abuts a residential district, a side yard of at least five (5) feet shall be provided.
b. 
Buildings shall be constructed from side lot line to side lot line, along the entire street frontage of streets designed or classified for the highest traffic volume. The developer shall have the option of excluding no more than twenty percent (20%) of the lots' frontage to create space for a public plaza or public green space area. This public space can be located no less than fifty (50) feet from any corner of the lot.
[Ord. No. 6276 §1, 6-25-2013]
Every principal commercial structure must provide off-street parking in accordance with Chapter 405.

A. 
Site Plan Review. Site plan review, pursuant to the procedures and standards outlined in Chapter 405, is required for any development or redevelopment proposal over ten thousand (10,000) square feet in gross floor area and for financial institutions that are proposed to be developed with drive-through facilities.
B. 
Site Plan Review Design.
1. 
The following criteria shall be applied by the City's Plan Commission/Architectural Review Board for development proposals located in the Maryland Gateway Overlay Zoning District:
a. 
Footprint geometry should be square and true with the roadway to the extent possible. Odd shapes and building orientations which compete with the total urban setting should be avoided.
b. 
Parking should be located within the City block interior and deeper into parcels.
c. 
Surface parking, drive aisles or vehicular access ways should not abut any sidewalk.
d. 
Buildings and uses must incorporate expansive street front windows and shall be sited in a manner so as to achieve a pedestrian friendly scale, appearance and feel.
2. 
For projects located in an underlying "C-2" zoning district, an on-site sidewalk system shall be constructed along a project's internal drives (both public and private) and shall connect to the public sidewalk system on Maryland Avenue and abutting streets. For these purposes, parking lot drive aisles are not to be considered drives or streets. Sidewalks shall also be constructed to lead to pedestrian crossings at off-site full access median openings, trail crossings, and pedestrian signal crossings on abutting streets.
3. 
The Plan Commission shall have the discretion to consider alternatives and modifications to these site plan review criteria if their strict application will result in unusual or practical difficulties, or a particular hardship, or if the Plan Commission determines that such alternatives or modifications to these guidelines will improve the attractiveness or usefulness of the district as a whole and serve the best interests of the City.
[Ord. No. 6276 §1, 6-25-2013]
A. 
The standards applicable to the Architectural Review Board are as follows:
1. 
Buildings shall occupy the property frontage from property line to property line to ensure a continuous building facade.
2. 
Building skylines should provide interest through introduction of compatible shapes and roof forms. Long uninterrupted rooflines and cornices should be avoided.
3. 
Facade relief should be incorporated into all building elevations. Long uninterrupted elevations should be avoided.
4. 
Window openings should be incorporated into all building elevations. Blank walls, long horizontal openings, odd shapes and glass walls should be avoided.
5. 
Street level (ground floor) elevation facing the street should be storefront architecture with large show windows interrupted at regular intervals with building piers and generous entrances. Blank walls, long uninterrupted show windows, odd-shaped and small show windows should be avoided.
6. 
Parking structures visible from the street should be avoided. Parking structures should be of design material and color compatible with the urban setting.
7. 
Building renovations and improvements should incorporate green space, pedestrian connections, pedestrian gathering spaces, street furniture and other elements of active pedestrian areas.
8. 
Building design should integrate components that offer protection to pedestrians, such as overhangs, awnings and canopies, as a means to encourage pedestrian activity along the street.
9. 
Building design should maintain and be compatible with the architectural character of the City's nearby residential and existing commercial neighborhoods.
