N-O District is intended to provide an area for professional and general offices, residential uses and for uses located in close proximity to associated uses, such as hospitals or public offices. The District is established for the purposes of selectively providing for well-planned land uses to be located between older residential neighborhoods and existing higher intensity nonresidential areas, such as corridor commercial, shopping center commercial, downtown commercial and industrial areas. It will provide for sites with yard, open space and architectural requirements similar to those in residential districts.
