C.

Building Articulation  

1.

Articulation in Building Height For buildings 150 feet or more in length, at least 15% of the street-facing roof line must have a variation in height of at least 5 feet. On a corner lot, the variation in height must be located at the corner of the building that addresses both street fronts. A parapet that meets the requirements of this Development Code may be counted toward this articulation requirement. Signs are not allowed above the roof line, and do not count toward this articulation requirement.

2.

Articulation in Building Facade For buildings 100 feet or more in length, at least 2 portions of the street-facing building facade must have a variation in setback of at least 2 feet. The combination of the required variations in setback must total no less than 15% of the length of the building.

D.

Ground Floor Retail Tenant Size In the City Springs and Perimeter Districts, no ground floor retail tenant may occupy more than 30,000 contiguous rentable square feet. No variances to this standard are allowed; however, the Director may approve renovation of existing tenant spaces so long as the renovation does not increase the gross square footage of an existing tenant space.
