A hotel or inn shall be permitted in an SP District if approved by the Board of Zoning Adjustment as a special exception under § 3104, subject to the provisions of this section.
[DELETED]
The height, bulk, and design of the hotel or inn shall be in harmony with existing uses and structures on neighboring property.
To ensure that the height, bulk, and design of the hotel or inn is in harmony with existing uses and structures on neighboring property, the Board may require special treatment in the way of design, building setbacks, screening, landscaping, sign controls, and other features as it deems necessary to protect neighboring property.
The approval of the hotel or inn shall result in a balance of residential, office, and hotel or inn uses in the SP District in the vicinity of the hotel or inn.
The gross floor area devoted to function rooms and exhibit space shall not exceed fifteen percent (15%) of the gross floor area of the hotel.
The hotel or inn shall be located within thirteen hundred feet (1,300 ft.) of the Central Employment Area or a Metrorail station.
The thirteen hundred foot (1,300 ft.) distance required in § 512.7 shall be measured from the entrance of the hotel or inn that is closest to the main lobby and guest registration desk to the edge of the Central Employment Area or the entrance to the Metrorail station, following public rights-of-way.
The Board may require more or less off-street parking spaces and loading berths than required by chapters 21 and 22 of this title to accommodate the activities of the hotel or inn, so as to avoid unduly impacting parking or traffic on the surrounding streets.
The location and design of driveways, access roads, and other circulation elements of the hotel or inn shall be to avoid dangerous or other objectionable traffic conditions.
