This district is established to provide for a limited range of nonresidential and noncommercial uses such as general purpose office, professional, or administrative operations. The district shall not permit those uses and activities pertaining to retail product display, installation, service, repair, or maintenance unless specifically provided for within the chapter. Among others, an objective of this district is to provide for a transitional buffer between the districts of lesser and greater intensity; and to restrict the intensity of use to a low to moderate range and to encourage a compatible design with the adjacent use and development. (Code 1995 § 48-12.00.)
