(B) Specific.

(1) Agricultural (A). The purpose of the A Zoning District is to protect and conserve agricultural lands and to support agricultural activities as an important contributor to the local and regional economy. The A Zoning District allows the production of crops, livestock grazing, animal and poultry raising, apiaries, dairies, stables and associated residences and farmworker housing. The A Zoning District is intended to protect land, including farmed or grazed wetlands, that is primarily suitable for long-term agricultural and wildlife habitat uses and to ensure adequate separation from adjacent development.

(2) Natural Resources (NR). The purpose of the NR Zoning District is to protect and restore land-based habitats and natural resources in Eureka. The NR Zoning District protects land that is primarily suitable for permanent habitat preservation, compatible resource-related uses, nature study and natural resource-related recreation. Public access, passive recreation, active recreation and visitor-related facilities are allowed to the extent such activities do not negatively impact or degrade natural resources. The NR Zoning District aims to protect surface water resources, riparian habits, ground water and water quality, sensitive biological resources and open space.

(3) Coastal zoning districts.

  • (a) The following resource-related zoning districts are located exclusively in Eureka’s coastal zone:

  1. Agricultural - Coastal (A-CZ);

  2. Natural Resources - Coastal (NR-CZ);

  3. Water Development - Coastal (WD-CZ); and
