   (b)   Overlay Zoning Districts.
      (1)   Some areas of the City may be divided into overlay zoning districts as established in Table 1104-1.
      (2)   As the name implies, overlay zoning districts are "overlaid" on top of base zoning districts where both districts affect the use of lots subject to those districts.
      (3)   Where land is classified into an overlay zoning district as well as a base zoning district, the regulations governing development in the overlay district shall apply in addition to the regulations governing the underlying base district. In the event of an expressed conflict between the standards of the overlay zoning district and the base zoning district, the standards governing the overlay district shall control.
   (c)   References to Previous Zoning Districts. Some of the district classifications and names established within this code differ from previous versions of this code. Table 1104-2 identifies how each of the previous district classifications were renamed in this code. This table shall be used for comparison purposes only.
