21A.30.020: D-1 CENTRAL BUSINESS DISTRICT:
   A.   Purpose Statement: The purpose of the D-1 Central Business District is to provide for commercial and economic development within Salt Lake City's most urban and intense areas. A broad range of uses, including very high density housing, are intended to foster a twenty four (24) hour activity environment consistent with the area's function as the business, office, retail, entertainment, cultural and tourist center of the region. Development is intended to be very intense with high lot coverage and large buildings that are placed close together while being oriented toward the pedestrian with a strong emphasis on a safe and attractive streetscape and preserving the urban nature of the downtown area. This district is appropriate in areas where supported by applicable master plans. The standards are intended to achieve established objectives for urban design, pedestrian amenities and land use control.
   B.   Uses: Uses in the D-1 Central Business District as specified in Section 21A.33.050, "Table of Permitted and Conditional Uses for Downtown Districts", of this title, are permitted subject to the general provisions set forth in Section 21A.30.010 of this chapter.
