SEC. 51A-4.125.   MIXED USE DISTRICTS.
   (a)   In general.  Single or multiple uses may be developed on one site in a mixed use district as in any other district; however, in order to encourage a mixture of uses and promote innovative and energy conscious design, efficient circulation systems, the conservation of land, and the minimization of vehicular travel, density bonuses are awarded to developments that qualify as “mixed use projects” as defined in Subsection (b).  If a development does not qualify as an MUP, it is limited to a “base” dwelling unit density and floor area ratio.  When a development qualifies as an MUP, it earns a higher maximum dwelling unit density and floor area ratio and, in some instances, a greater maximum structure height.  Additional FAR bonuses are incrementally awarded to encourage the inclusion of “residential” as part of an MUP.  The exact increments of increase vary depending on the actual use categories mixed and the district that the MUP is in.  For more information regarding the exact increments of increase, consult the yard, lot, and space regulations in this section governing the particular district of interest.
   (b)   Qualifying as a mixed use project.  To qualify as a MIXED USE PROJECT (MUP) for purposes of this section, a development must contain uses in two or more of the following categories, and the combined floor areas of the uses in each category must equal or exceed the following percentages of the total floor area of the project:
