313-1 Lists of Zone Mapping Designations and Lists of Permitted Use Types

The Principal Zone is the first zone designation applied to property which designates the principally permitted uses on the property. The Principal Zoning Districts in the Coastal Zone shall be represented on the adopted zoning maps by the designations in the following table. An explanation of what is allowed in each district follows this list. Definitions and terms used (such as “use type”) are explained in Section C: Index of Definitions of Language and Legal Terms, below.

Beginning with Section 313-2, Section A, Part 1 of this Chapter contains a list of permitted use types in the Principal Zones. These use types are listed by zone district, and are permitted pursuant to the Development Permit Procedures in Chapter 2 of this division. Definitions and terms used (such as “use type”) are explained in Section C: Index of Definitions of Language and Legal Terms. Full descriptions of each use type are found in Section D, Part 2: Glossary of Use Types.
