Within the Hospital Parcel, the applicant proposes the establishment of three building height zones with minimum setbacks and building massing design standards. The three height zones are for three-story, four-story, and five -story buildings. The standards include different maximum heights for the buildings, the parapets, and mechanical screen structures as noted in Figure 9 below. Due to some of the unique requirements for hospital and medical office developments, the proposed maximum heights are taller than what would be expected in non -medical office buildings. The proposed building massing design standards would require building step -backs of 15 feet for building elements above 45' and limit the footprint of building elements above 45' to 5013/0 of the lower building footprint. This is intended to moderate the visual impacts of the building massing for taller buildings. The proposed standards also include allowances for architectural projections and "defining architectural elements," including requirements for depth variations for these elements. Rooftop enclosures would need to be set back an additional 10' from the edge of the buildings.
