9.05.030: ESTABLISHMENT OF BASE ZONING AND OVERLAY DISTRICTS:
   A.   General: The town is divided into zoning districts to allow for the orderly development of the town and to implement the general plan. Table 2-1 of this section identifies all zones. All zones shall be listed and appropriately designated on the official zoning map.
   B.   Base District: Every parcel shall have a base zone that establishes the primary type and intensity of land use permitted, along with development regulations for that particular type and intensity of land use. The base zoning districts are described in chapters 9.07 through 9.13 of this article 2.
   C.   Overlay District: An overlay zoning district supplements the base zone for the purpose of establishing special use or development regulations for a particular area in addition to the provisions of the underlying base zone. In the event of conflict between the base zone regulations and the overlay zone regulations, the provisions of the overlay zone shall apply. The overlay zoning districts are described in chapters 9.15 through 9.22 of this article 2.
