The maximum number of dwelling units permitted at the Tract, comprising Block 3301, Lot 2, and Block 3401, Lots 11, 12, 19, 40-43, 52, 53, 57, and 58, is 240, which shall include 20% of units designated as affordable units. Financial arrangements, separation of ownership units and rental units, and ultimate ownership of the property may result in subdivisions whereby market-rate and affordable units are on different lots. This section also anticipates that market-rate townhouses may be on individual fee-simple lots and specifically permits the same. The bulk standards for this particular section apply to the Tract, specifically the RA-6AH Zone boundary lines, not lot lines, and are not intended to thwart the purpose and design intent of the RA-6AH Zone as expressed herein.
