A. 
Purpose. The purpose of these architectural and design standards is to ensure the highest quality and most aesthetically pleasing development in all areas of the City. Redevelopment and new development in the City reflects on the image of St. Charles and it is crucial that new structures and rehabilitation or additions to old structures adhere to a higher standard to reflect positively on the City's progressive attitude toward its future. These standards are not intended to restrict imagination or variety, but rather to assist in focusing on a design which results in an architectural style that creates a signature appearance that is distinctly St. Charles.
B. 
Architectural And Design Standards. These architectural and design standards shall apply to all new structures (as structure is defined in the building code), reconstruction of structures, rehabilitation of structures and expansion of structures in all zoning districts, except: (1) single-family and two-family residential structures; (2) all structures legally existing or for which building permits have been legally approved on or prior to December 1, 2003; and (3) structures which have previously been approved pursuant to Section 400.980(I) where said approval authorized the use of specific building materials. Architectural and design standards shall be defined as follows:
