The city and its jurisdictional area is divided into the following districts:
(A) Agriculture Districts, designated A, are established to include substantial areas where little or no urbanization has occurred or is likely to occur in the near future and where the predominant use of land involves crop production, raising livestock or similar farming.
(B) Conservancy Districts, designated CD, are established to protect environmentally sensitive areas, as well as include areas for public parks and recreation areas. No principal structures should be permitted for any use in a conservancy district. These areas may be used for agriculture, conservation or may be included in computation of residential lots, yards or other open spaces.
