[Ord. No. 5906 §3(12a.1), 10-25-2005]
The general intent of these regulations and standards is to minimize the impact of future development within the Clayton Road Urban Design District ("CR-UDD") on adjacent residential neighborhoods, promote a mixed-use/residentially-oriented pattern of development that is more compatible with the adjacent neighborhoods than traditional commercial uses found in other areas of the Clayton Road corridor, to increase the predictability and flexibility of future development within the "CR-UDD" and to maintain the "CR-UDD" a visually appealing gateway for the City of Clayton and the adjacent neighborhoods.
[Ord. No. 5906 §3(12a.2), 10-25-2005]
The Clayton Road ("C-2") Urban Design Zoning District encompasses the properties fronting the north side of Clayton Road from Big Bend Boulevard to the east City limits as depicted on the map below:
[Ord. No. 5906 §3(12a.3), 10-25-2005]
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. 5906 §3(12a.4), 10-25-2005]
The uses permitted by right and by conditional use permit are listed in the Table of Permitted Uses found at the end of this Article. If a "P" (permitted by right) or a "C" (permitted by conditional use permit) is not indicated for a use in the Table, it is prohibited.
[Ord. No. 5906 §3(12a.5), 10-25-2005]
This Section provides definitions specific to the "CR-UDD". Definitions governing all urban design districts inclusive of the "CR-UDD" are found in Chapter 405.
LIVE/WORK UNIT
A structure with a combination of uses where work activities occur and a dwelling unit is included for the business occupant. Such unit shall have only one (1) kitchen and not more than fifty percent (50%) of the structure shall be dedicated for a business use. The dwelling unit shall be occupied by either the owner, the tenant or the owner or tenant's employee. The residence must be the residence of a person responsible for the work performed on the premises.
MAXIMUM EXTENT PRACTICABLE
It is the responsibility of the developer to show clearly and convincingly to the satisfaction of the Plan Commission that, under the circumstances, reasonable efforts have been undertaken to comply with the regulation or requirement, that the cost of additional compliance measures clearly outweigh the potential benefits to the public or would unreasonably burden the proposed project and reasonable steps have been undertaken to minimize any potential harm or adverse impacts resulting from non-compliance.
MIXED-USE DEVELOPMENT
Development containing a mix of complimentary uses within the same building. Typically, mixed-use buildings contain some combination of retail, office and residential uses, with retail uses located at the ground floor and office or residential uses located above. Residential uses shall contain a floor area no less than seven hundred fifty (750) square feet.
[Ord. No. 5906 §3(12a.6), 10-25-2005]
A. 
This Section provides the following standards designed to maintain the pedestrian-oriented, landscaped character of the front setback (where still evident), to avoid creating an imposing, "canyon" of taller buildings along Clayton Road and to establish intersections within the "CR-UDD" as prominent gateways to the adjacent neighborhoods.
B. 
Front setback may be reduced to twelve and one-half (12.5) feet for mixed-use development located on corner lots. Reduced setback shall be allowed within sixty (60) feet of the applicable intersection (as measured from the property line at the back of the sidewalk) and shall only be applicable to lots adjacent to the following intersections:
1. 
DeMun Avenue and Clayton Road;
2.

1. 
Residential and mixed-use developments shall have no more than thirty percent (30%) of the required front yard setback covered by impervious material. This standard shall not be applicable to commercial development and shall only be applicable to the portion of a corner development where a reduced front setback is not permitted. If a corner development does not opt to reduce the front setback for the area permitted, the above provision would apply to the entire lot frontage.
2. 
Surface parking shall be prohibited between the site's primary building and Clayton Road.
[Ord. No. 5906 §3(12a.8), 10-25-2005]
