14-2G-3: SUBDISTRICT STANDARDS:
   A.   South Downtown, Park, South Gilbert, And University Subdistricts:
      1.   Intent: The South Downtown, Park, South Gilbert, and University Subdistricts of the Riverfront Crossings District (shaded in dark in figure 2G-3 of this section) are intended for high intensity mixed use development in buildings with active ground floor uses opening onto pedestrian friendly streetscapes. Buildings are designed with facades aligned along public sidewalks with parking and service areas located behind buildings in rear lot and midblock locations.
The University Subdistrict is intended for continued use by the University Of Iowa. While not subject to these standards, new and renovated university facilities should adhere to the standards to the extent feasible. Properties within the University Subdistrict that are not owned by the University of Iowa, however, must fully comply with all applicable standards below.

For multi-family uses, the provisions in section 14-4B-4 of this title are superseded by the standards in this article, and therefore, do not apply. Residential occupancy is limited to one "household" per dwelling unit, as this term is defined in chapter 9, article A, "General Definitions", of this title. The residential occupancy of a household living use is constrained by the provisions of title 17, chapter 5, "Housing Code", of this Code. The maximum number of bedrooms per dwelling unit is three (3). Residential density (units per acre): no maximum. However, in the South Downtown and University Subdistricts for apartment buildings, multi-dwelling buildings and mixed use buildings the number of three bedroom units per lot may not exceed thirty percent (30%) of the total number of units on the lot.
