StE  
The Saint Elizabeths East (StE) District was established to provide for a broad mix of uses, including residential, commercial, hospitality, educational and civic uses consistent with the Saint Elizabeths East Master Plan and Design Guidelines. The purposes of the StE District are to reinvigorate the campus as an important neighborhood center, preserve and adaptively reuse historic resources, and enhance the unique and historic identity of the campus through new development. The new Saint Elizabeths East (StE) District will have nineteen (19) subdistricts, StE-1 through StE-19. Each StE subdistrict will have its own bulk and design provisions, including height, density, lot occupancy, and street frontage requirements for unique conditions associated with the historic nature and architecture of the campus. New parking spaces on the campus will be limited to four thousand eight hundred (4,800) spaces, which will be monitored through each building permit granted. Most of the uses within the StE District will be as a matter-of-right except for a few which will be permitted by special exception or are prohibited. Building heights range from zero (0) to ninety (90) feet with the tallest buildings away from the historic buildings. The proposed building heights address the context of existing to new buildings and allow heights to transition down to adjacent historic buildings. To ensure that the overall development maintains the mix of uses envisioned across the campus, a portion of the overall FAR within seven (7) of the subdistricts is required to be dedicated to residential use. To provide further flexibility, residential use can be transferred to properties located in other specified subdistricts through a combined lot mechanism, provided the maximum total density and height for the receiving subdistrict remains as specified for that subdistrict. Within the StE-7, 15, and 17 subdistricts, additional FAR for above-grade structured parking is provided.
