For multifamily residential, the total maximum allowable residential density for both the Olmsted East Mixed Use Subdistrict and the Olmsted West Residential Subdistrict shall be thirty-two (32) units per acre of Developable Land, as defined in Chapter 40R. Residential density shall be calculated for the entirety of each subdistrict regardless of whether the residential density of individual parcels or Proposed Projects within a subdistrict meets the minimum density set forth in this subsection 87A-7.2.

On-street parking created on new streets constructed as part of a Proposed Project shall count toward the above off-street parking requirements.
