§ 21-3.90-1 Apartment mixed-use district uses and development standards.

(a)   Within the apartment mixed-use districts, all uses and structures are as set forth in Table 21-3.

(b)   Within the apartment mixed-use districts, development standards are as set forth in Table 21-3.3.

(c)   Additional development standards.

(1)    Except for necessary access drives and walkways, all yards must be landscaped.

(2)   Height setbacks. In the AMX-2 and AMX-3 districts, for any portion of a structure over 40 feet in height, additional side and rear setbacks must be provided as follows:

(A)   For each 10 feet of additional height or portion thereof, an additional 1-foot setback must be provided; and

(B)   The additional setback must be a continuous plane from the top of the structure to the height of 40 feet above grade (see Figure 21-3.3).

(3)    Commercial use density and location.

(A)   The floor area of any use marked with a superscript1 under Table 21-3, either occurring as a single use on a zoning lot or in combination with other uses, must not exceed the FAR as provided under Table 21-3.3, and such floor area will be counted as part of the total FAR allowed.

(B)   Where commercial uses are integrated with dwelling uses, pedestrian access to the dwellings must be physically, mechanically, or technologically independent from other uses and must be designed to enhance privacy for residents and their guests. No floor above the ground floor may be used for both dwelling and commercial purposes.
