   (h)    C-1 CBD Central Business District. The purpose of the CBD District is to encourage the viability of the commercial core of the City. By locating more intensive commercial uses in close proximity to each other, each use will support and benefit the others.
   (i)    C-2 General Commercial District.

   (j)    I-1 General Industrial District. The purpose of the I-1 District is to reflect the existing pattern of industrial establishments in the community, to allow for their future expansion and to delineate additional industrial land for new industry. The intent is to designate those lands that have the best industrial development potential by virtue of good access to the State Highway network and/or railroad right of way; that are capable of being fully served by all necessary utilities; and are somewhat removed from adjacent residential development and housing.
