Administrative office districts, hereinafter designated as C-O districts, are established to provide for the location of offices for professional services and for business activities which are characterized by a low volume of direct consumer contact; and to encourage such development in a manner compatible with the uses in adjacent districts, with suitable open spaces, landscaping and parking area, C-O districts are typically situated in areas having convenient access from, but not directly on, main thoroughfares, and generally adjacent to a multiple residential development.
