13.10.312 Uses in agricultural districts.

(a) Principal Permitted Uses.
1. In the Coastal Zone, the principal permitted uses in the agricultural districts shall be as follows:
“CA” and “AP”: agricultural pursuits for the commercial cultivation of plant crops, including food, fiber, flower or other ornamental crops and the commercial raising of animals, including grazing and livestock production, and apiculture and accessory uses and structures, excepting those agricultural activities listed as discretionary uses requiring a Level V or higher approval.
“A”: agricultural pursuits, including the noncommercial or commercial cultivation of plant crops or raising of animals, including apiculture, single-family residential and accessory uses and structures, excepting those agricultural activities listed as discretionary uses requiring a Level V or higher approval.
2. Principal permitted uses are all denoted as uses requiring a Level IV or lower approval or as otherwise denoted with the letter “P” in the Agricultural Use Chart contained in paragraph (b) below. In the Coastal Zone, actions to approve uses other than principal permitted uses are appealable to the Coastal Commission in accordance with the provisions of Chapter 13.20 of the County Code relating to Coastal Zone approvals, and in some cases, as specified in Chapter 13.20, any development is appealable.
(b) Allowed Uses. The uses allowed in the agricultural districts shall be as provided in the Agricultural Uses Chart below. A discretionary approval for an allowed use is known as a “Use Approval” and is given as part of a “Development Permit” for a particular use. The type of permit processing review, or “Approval Level,” required for each use in each of the agricultural zone districts is indicated in the chart. The processing procedures for Development Permits and for the various Approval Levels are detailed in Chapter 18.10 PERMIT AND APPROVAL PROCEDURES. The Approval Levels given in this chart for structures incorporate the Approval Levels necessary for processing a building permit for the structure. Higher Approval Levels than those listed in this chart for a particular use may be required if a project requires other concurrent Approvals, according to Section 18.10.123. All Level V or higher Approvals in the “CA” and “AP” zone districts are subject to the special findings required by Section 13.10.314(a) in addition to those required in Section 18.10.230.
